This market is a market that is manipulated. We have miners who verify transactions, have additional insider trading floors, ICOs, pump and dump assemblies, sharks and whales, things they do. is to make a profit for themselves rather than anyone else. With a person you do not know, do you think they can withstand heat? There may be people who are really good but no one can say anything, preferably not one.
Second, the cryptocurrency market is not like the stock market, in cryptocurrency we have cryptography, blockchain technology, market psychology, economics, etc., and many other applications can be applied to the field, So when someone says they are expert in the field of cryptocurrency, get them aside.
Do not react too quickly, never invest on a hype and wait it out, even if you are going to buy something for sure, sleep on it and wait for the next day, if you did your research and know what you are going to buy and you are sure for it and slept on it and the next day you are still interested on that than you can buy it.
Before all of this if you buy on a hype and get the feeling of you are going to become rich you will be sad for a long time. My friends who made the most of crypto world have consistently be the ones who took the smaller gains instead of waiting for the 10x or so returns, they just get that 5% and leave it alone.
