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.
