Why most of Traders have bad psychology of trading they keep lose more and more and can lost his account and they left quickly when operations is winning?
The problem about traders is that, they tend to invest when the market prices are still high and they will complain their loss when the prices dump after a few months due to volatility.
You mean the problem with BAD traders is all that. The real problem with most crypto traders is that they don't believe in coins they buy, they just want more money so when the prices fall they sell in panic.
