Manipulation, deception, and theft are big problems in crypto. If you try to day trade you will lose your shit because of the candle wicks by whales. The best thing is to just hodl and ignore all the negative news which is usually false anyways.
Deception and manipulation are the norm and the rule in every market, it is not clear why the crypto market should be different.
Obviously, since it is a small market, with few players compared to the stock exchange or the forex, it is infinitely easier for the whales to succeed.
