As a beginner, it is important to remember these key points to avoid losing money when investing in coins:

1. Don't be fooled by posts claiming huge profits in a short period of time. Chances are you won't be able to replicate these results without extreme luck. Gambling and lotteries have a higher winning percentage.

2. Be careful when blindly investing your hard-earned money. Why work hard for fiat currency just to buy what the seller chooses? Will they offer you better options or just some old junk?

3. Don't blindly follow signals. Do you really know the person behind that username and their reputation? They may have been lucky in the past, but this could lead to significant losses for you. Do they even care about $5,000? You?

4. Be skeptical of influencers. They are here to manipulate the market and make money for themselves, not you. They may artificially create rumors without any reasonable basis. Beware of "MUST BUY" messages because you never know when they will drop the product.
