How to Track Stock Prices and Buy Shares — Simple Guide for Beginners (2025)

Introduction

Investing in stocks is no longer reserved for wealthy people or professionals.
Today, anyone can track stock prices and buy shares — even with a small budget — using simple online tools.

This guide explains:

how to track stock prices
how to buy shares
minimum investment amounts
fractional shares
practical examples

Everything explained in a clear, beginner-friendly way.

1. How to track stock prices

Best free tools:

✔ Google Finance
✔ Yahoo Finance
✔ Investing.com
✔ Your broker’s app

Example current prices:

Apple (AAPL) — ~$266
Microsoft (MSFT) — ~$478

What to look at besides price:

1-year and 5-year chart
long-term growth stability
P/E ratio (valuation)
market capitalization

This helps you understand if a stock is stable or volatile.

2. How to buy shares

Step 1: Choose a broker

Popular options that accept users from Serbia/Europe:

eToro
Interactive Brokers
Trading 212
Revolut (Invest)

Step 2: Verify account (KYC)

ID + proof of address.

Step 3: Deposit funds

Credit/debit card or bank transfer.

Step 4: Find the stock

Search by ticker:

AAPL
MSFT
KO
PG
NVDA

Step 5: Buy

Choose:

Market order — buys instantly
Limit order — buys at your chosen price

3. Do you need to buy multiple shares? (NO!)

You can buy just one share.

Example:

Apple = $266
Microsoft = $478
Coca-Cola = $59

But there's an even better option:

4. Fractional Shares — buy a “piece” of a stock

If a stock costs $1000, you can still invest as little as $5.

You buy a fraction of the share.

This is perfect for beginners and small budgets.

5. How much money do you really need?

For learning → €20–50
For long-term investing → €100–500 per month (optional)

Small, consistent investments work better than big, rare ones.

6. When is the best time to buy?

If you’re a beginner:

Don’t try to time the market.

The best approach is:

✔ buy regularly
✔ monthly or weekly
✔ long-term focus

This is called Dollar-Cost Averaging (DCA).

7. Track your portfolio

Check periodically:

total invested
total value
profit/loss
whether you want to buy more

For long-term investors — checking once per month is ideal.

Conclusion

Stock investing is simple, accessible, and doable with very small budgets.
The key is:

consistency
education
long-term mindset

Even 20–50€ monthly can build a serious portfolio over the years.

THE ANATOMY OF A CASINO — THE MACHINE DESIGNED TO WIN

🎰 THE ANATOMY OF A CASINO — THE MACHINE DESIGNED TO WIN

THE ULTIMATE EXPOSÉ OF PSYCHOLOGY, TECHNOLOGY, AND FINANCE BEHIND GAMBLING

🔥 INTRO — A WORLD BUILT TO CONTROL YOUR PERCEPTION

Most people enter a casino thinking they are entering a playground of luck, chance, entertainment, and possibility.

But the truth is darker, deeper, and more engineered.

A casino is not a playground.
A casino is a behavioral, technological, statistical machine.

A casino is:

A psychological laboratory.
A controlled environment.
A statistical system.
A multi-billion dollar financial engine.
A perfectly tuned dopamine manipulation mechanism.

You don’t play against “luck”.
You play against a system built to win — slowly, silently, and with absolute consistency.

Let’s open the machine.

🟥 PART 1 — THE MATHEMATICS THEY DON’T WANT YOU TO UNDERSTAND

🔢 THE HOUSE EDGE: THE CORE OF THE SYSTEM

Every casino game is built with a mathematical parameter called house edge.

This is the percentage of your bet the casino expects to keep on average:

Roulette: 2.7%–5.26%
Slots: 4%–20%
Blackjack: 0.5%–2%
Sportsbooks: 5%–12% margin
Keno: up to 25%

The longer you play → the closer your results converge toward inevitable loss.
The more rounds you play → the more money the casino extracts.

This is not a theory.
It is a law of large numbers.

🎰 THE RTP ILLUSION — PLAYER MISUNDERSTANDING #1

RTP (Return To Player) is not a promise to the player.

RTP is a promise to the casino.

RTP is calculated over:

1,000,000 spins
10,000,000 spins
sometimes 100 million simulations

Meaning:

👉 Your 200–500 spins mean nothing statistically.
👉 Your small session is pure randomness.
👉 RTP guarantees the casino their profit — not you yours.

This is the core misconception that keeps people trapped.

🧠 PART 2 — PSYCHOLOGY: HOW THE CASINO BREAKS YOUR SENSE OF REALITY

(Suggested illustration #2: slot symbols in “near-miss” sequence)

Modern casinos rely on decades of behavioral psychology research, including work by:

B.F. Skinner
Daniel Kahneman
Amos Tversky
Robert Cialdini

Casinos use every known psychological vulnerability of the human brain.

Let’s break the biggest ones.

⏳ 1. Time Dissociation — Casinos Erase Your Internal Clock

Why are there:

no windows?
no clocks?
uniform lighting?
controlled temperature?

Because casinos want you to:

lose time awareness
enter a flow state
forget external obligations
keep playing

A casino is designed to suspend reality.

🔊 2. SOUND DESIGN — THE INVISIBLE MANIPULATOR

Slot machines use reward sounds even when you lose.

Example:

You bet 1$
You win 25 cents
The machine plays a victory jingle.

Your brain registers:

👉 “I won!”

But mathematically:

👉 You lost 75%.

This is engineered cognitive distortion.

🎨 3. VISUAL ENGINEERING — THE NEAR-MISS EFFECT

Humans react to “almost winning” with the same dopamine response as winning.

Slot designers exploit this ruthlessly:

🍒 🍒 ❌
⭐ ⭐ ❌
7️⃣ 7️⃣ ❌

This effect is not random. It is coded.

“Near-misses” are placed at frequencies proven to increase playtime and losses.

🟥 4. THE FLOOR PLAN — EVERY INCH IS MANIPULATION

Casinos use heat maps to track where players:

walk
stop
hesitate
cluster
lose
win

The layout is optimized using real-time behavioral data.

Casinos place:

high-volatility machines in dark corners
low-volatility “safe” machines near entrances
“hot machines” where passing players can hear frequent wins
high-limit tables in isolated, psychologically stimulating environments

The entire floor is engineered to keep you inside longer.

🟪 5. SURVEILLANCE — THE EYE IN THE SKY IS NOW AI

Gone are the days of simple dome cameras.

Modern casinos use:

facial recognition
emotion recognition
betting pattern analysis
RFID tracking
AI-based fraud detection
occupancy heat maps
posture analysis
player profiling algorithms

Casinos predict your emotional state and adjust offers, comps, and interactions accordingly.

🟦 6. RFID CHIPS — YOU ARE ALWAYS BEING TRACKED

Every casino chip is embedded with RFID technology.

The system knows:

how many chips you have
how quickly you’re betting
what patterns you follow
when you take risks
when you switch strategies
when you enter a “tilt state”

This isn't a game.
It's a behavioral database.

🟫 7. OCR CARD TRACKING — THE END OF CARD COUNTING

Every card dealt at live tables is scanned via:

invisible UV markers
high-speed OCR cameras
table-level processors

The casino knows:

card order
dealer patterns
player risk patterns
abnormal behaviors

If you play “too well”, the system flags you.

And the table suddenly “closes”.

🧨 PART 3 — THE PEOPLE WHO TRIED TO BEAT THE SYSTEM

(Suggested illustration #3: a black-and-white dramatic casino scene)

🧮 Ed Thorp — the mathematician who broke blackjack

Created the first card-counting system.
Won consistently.
Casinos banned him globally.

🎓 MIT Blackjack Team

Millions earned.
Systematic teamwork.
Iconic strategy.

Eventually — banned everywhere.

🎥 The Roulette Physicists

Using:

concealed cameras
micro-computers
ball speed analysis
wheel bias calculation

They predicted “number clusters” with terrifying accuracy.

Casinos rewrote their rules because of them.

🛠️ The Russian Slot Hackers (2017)

Recorded slot machine vibrations via smartphone.
Fed the data into an AI model.
Predicted payout windows.

Pulled millions before being caught.

💸 PART 4 — WHO ARE THE BIGGEST LOSERS? (REAL GLOBAL DATA)

1. IT workers (programmers, engineers, analysts)

Think in patterns → try to “solve the machine”.
Impossible.

2. Entrepreneurs

Addicted to risk.

3. Professional athletes

Impulse-driven, competitive, wealthy.

4. Low-income players

Slots specifically exploit this demographic.

5. Bankers / executives

VIP rooms drain fortunes silently.

🟨 PART 5 — THE BIGGEST MYTH IN GAMBLING: “THE MACHINE IS DUE”

This is 100% false.

A slot machine:

has no memory
does not “build up”
does not “owe a jackpot”
cannot be “due”
does not care how long you've played
is not influenced by time or amount wagered

Every spin is independent.

This is the hardest truth for gamblers to accept.

🟥 PART 6 — CAN YOU BEAT THE CASINO?

Short answer:

✔️ YES — in the short term.

Anyone can hit a jackpot.

❌ NO — in the long term.

No human can defeat math.

The system is built on:

statistical dominance
psychological engineering
surveillance
AI risk detection
deep behavioral data
massive bankroll advantage

You are not playing “a game”.
You are engaging with a financial weapon built to extract capital.

🟩 THE FINAL TRUTH — THE UNSPOKEN REALITY OF GAMBLING

Casinos are not about luck.
Casinos are not about entertainment.

They are:

dopamine factories
financial vacuum systems
behavioral experiments
statistical fortresses
psychological traps
and perfectly optimized money engines

Casinos are the only business in the world where the customer believes:

👉 “I can beat the system.”

While the system knows:

👉 “You are part of the data set.”

And in the end:

The house always wins — not because of luck, but because it designed the entire universe you are playing in.

5 Typical Failures of LED TVs, symptoms, fault identification and potential solutions - from the position of an experienced service technician!

Nowadays, LED TVs are popular, and they got their name from the type of backlight. LED backlighting, for the light source (WHICH ILLUMINATES THE IMAGE), uses LED (Light emitting diodes) diodes that emit light.

WHAT ARE THE TYPICAL PROBLEMS OF SMART LED TVS?

FAILURE #1: LED backlight goes out

LED backlighting is the first to fail on current LED TVs. You are left with no image and the sound is present. Actually the image is present but not visible because it is not illuminated.

We do not advise you to try to replace the LED strips yourself because the panel (display) on the LED TV is only slightly more than 1mm thick, and if you do not have experience, the probability of breaking it is very high.

If this happens, either you have permanently lost the TV, or the cost of replacing the panel and backlight will question the profitability of such an undertaking, it will be more than the price of a new TV.

An authorized TV service replaces the backlight, quickly, efficiently and with compatible led strips, but also with a guarantee.

It also successfully solves all other potential faults on LCD TVs.

Photo: LED TV backlight

Newer TVs are now mostly SMART versions, which means they have the ability to connect to the Internet, use the Android operating system, and applications that are massively used in that system, such as YouTube, Chrome, Facebook, Netflix, etc.

The connection is mostly WiFi (wireless), but it is also possible to use a wired network cable. As a service technician, I can say that the stability of those smart TVs is not at an enviable level, especially when you are often on the Internet, because you are actually exposed to various malicious software threats.

Failure No. 2 : Android System Crashes

There is a system crash and Android can't boot up, so as a result the tv just spins the manufacturer's LOGO and can't boot up the system!

What is the solution in those situations? The solution is to reinstall the operating system.

The installation is recorded on a USB flash memory, inserted into the TV's USB port and the system is reinstalled with the appropriate procedure.

Reinstallation is possible if the motherboard is correct, i.e. if there is a correct EMMC or NAND chip on the motherboard, the system installation is written into that chip.

For more serious manufacturers, you can find the software on the official website of the TV manufacturer, on the support page. You have to keep in mind that when you buy a cheaper television set from a non-reputable manufacturer, you don't have any online support, outside the warranty period, and often during the warranty period.

photo: reinstall software on your TV

FAILURE No. 3: MOTHER BOARD FAILURE

The motherboard is often under attack, when there are atmospheric discharges and thunderstorms in your area. The high voltage produces an electric shock, and through the receiver and HDMI cable, it directly burns the processor and thus the motherboard is dead. If the impact is weaker, it often causes only the failure of the HDMI input to begin with, but later the rest (the processor) also fails.

When the processor is dead, the motherboard is also dead, it does not respond to the remote control and the signal light does not light up, or it may light up but not respond.

In such cases, the solution is to replace the motherboard. Motherboard repair in the sense of processor replacement can only be done by highly specialized services, but this endeavor is usually as expensive as a new motherboard.

Photo: LED TV Mainboard

Failure No. 4. On the screen you see horizontal or vertical lines (Stripes), which either vibrate or are still, even worse you have a blank screen in front of you!

As TV technology develops, so does the resolution of the built-in panels. Now popular are 4K (UHD) panels, whose resolution is 3840x2160. That's double the previous FHD (Full HD). And our service experience is that they break down twice as often. As TVs get bigger, 55", 65", 75", 85", etc. thus, the demands of making such panels are increasing.

Mounting large LED TVs on the wall - EXPERIENCES

As a service, I want to share the experience gained during many years of work related to hanging large LED televisions on the wall. Such TVs often arrive at the service center with a defective panel or screen. We concluded that almost 80% of those devices were hung on the wall. The explanation is as follows: The chassis of the TV is made of a relatively thin sheet, and when you screw it to the holes left for this in the middle, there is a certain distortion of the chassis (due to the weight of the device itself), and therefore there is pressure on the panel. The panel is glass with a thickness of only 1-2 mm and the lines inside the glass also suffer from this distortion and loosen over time. A power failure occurs in the side image drivers, and the image is either lost or distorted. There is usually no help, that is, the only solution is to replace the panel, and it is either not available or too expensive!!!

Conclusion: placing the TV on a stand is a safer option per panel (screen)!!!

photo: LED TV displey (panel) problem

Fault no. 5. Failure of the power supply board on the TV

Voltage oscillations, thunder, or poor quality of the components in the power supply part of the board, can result in failure of the TV power supply.

Up until now, more serious televisions generally had a separate power supply and processor part, that is, a separate power supply and processor board.

However, more and more, mainly due to savings, these two plates are joined into one. This certainly reduces the quality of the TV set, i.e. increases its vulnerability.

How to Seriously Speed Up Your Laptop or Desktop PC — With a Justified Budget (2025 Guide)

Introduction

A slow computer usually doesn’t mean it’s outdated. In over 80% of cases, performance can be dramatically improved with small upgrades or free optimizations. Here are the most effective and financially justified methods.

1. Upgrade to an SSD — the biggest performance boost

If your computer still uses an HDD, replace it first. An SSD makes your system up to 10× faster.

faster booting
faster program loading
improved game performance
faster file transfers

Why this upgrade is worth it:

huge performance boost for low cost
very reliable
long lifespan

2. Increase your RAM

4 GB RAM is extremely slow today. Ideal amounts:

8 GB – normal users
16 GB – productivity and multitasking
32 GB – video editing, CAD, heavy apps

3. System cleanup (free and very effective)

uninstall unnecessary apps
disable startup programs
clean temp files
scan for malware

Recommended tools: Task Manager (Startup), Microsoft PC Manager, Malwarebytes.

4. Thermal cleaning and new thermal paste

Overheating slows down the CPU (thermal throttling). Signs:

loud fan noise
the laptop gets hot quickly
slowdowns after a few minutes

5. Reinstalling Windows

If your system is messy, full of errors or old drivers, a fresh install restores full speed.

install drivers manually
avoid cracked software
create a restore point

6. When upgrades are NOT worth it

laptops older than 10 years
weak CPUs (old Atom, Celeron)
motherboard issues
multiple hardware failures

Conclusion

The most cost-effective performance improvement is a combination of SSD, RAM, system optimization, and thermal service. This guarantees maximum performance for years.

Typical Router Problems and How to Fix Them (Updated 2025)

Introduction

Your router is the heart of your home network. If your WiFi keeps dropping, speed is inconsistent, or devices randomly disconnect — the issue is usually a simple configuration problem, interference, or an aging router.
Here is a complete guide with real-life, practical fixes based on years of hands-on experience.

1. Weak WiFi signal in certain rooms

Symptoms:

full bars but slow speed
WiFi disappears in the bedroom/kitchen
speed much lower on phones than on a laptop near the router

Causes:

walls, tiles, concrete
interference from microwaves, Bluetooth, smart devices
poor router placement

Fix:
✔ Place the router higher and centrally
✔ Don’t hide it behind a TV or furniture
✔ Enable 5GHz (faster, cleaner signal)
✔ For larger homes: use a WiFi extender or mesh system

2. Internet works sometimes, then stops (intermittent connection)

Causes:

router overheating
outdated firmware
network congestion

Fix:
✔ Restart router for 30 seconds
✔ Update firmware from admin menu
✔ Keep router in open, ventilated space
✔ If over 4 years old — consider replacement

3. Slow speed despite having a good internet plan

Causes:

overcrowded WiFi channel
old 2.4GHz router
wrong channel settings

Fix:
✔ Switch to a less crowded WiFi channel
✔ Use 5GHz when possible
✔ Scan signals using “WiFi Analyzer”
✔ Consider buying your own, better router

4. Devices connect to WiFi but have no internet

Causes:

ISP issue
DNS failure
wrong IP assignment

Fix:
✔ Test connection via cable
✔ Set manual DNS (Google DNS):
8.8.8.8 / 8.8.4.4
✔ Restart router and modem

5. Devices refuse to connect (password error, WPS, DHCP)

Fix:
✔ Disable WPS
✔ Change SSID + password
✔ Ensure DHCP is ON
✔ If nothing helps — factory reset (10 sec button)

6. Router freezes or restarts by itself

Causes:

overheating
faulty power adapter
weak hardware
corrupted firmware

Fix:
✔ Improve airflow
✔ Replace adapter
✔ Update firmware
✔ Replace router if crashing under heavy load

7. Interference in apartment buildings (2.4GHz)

Fix:
✔ Use 5GHz whenever possible
✔ On 2.4GHz stick to channels 1, 6 or 11
✔ Re-test using “WiFi Analyzer”

8. When should you replace your router?

Replace if:

older than 5 years
lacks 5GHz
overheats
unstable under multiple devices
WiFi much slower than cable

Conclusion

Most router problems are easy to solve once you know where to look. If issues persist, the router is likely outdated or the problem is coming from your ISP line.
