A lot of people get rich from bitcoin and also a lot of people fail from bitcoin, why do i say that??. The price of bitcoin is always volatile and a lot of people go into the crowd when they join, and they swing high and low
It's the nature of trading. Even if it's not volatile, There will be a lot of people losing their money if many is winning since trading is just transferring of asset from impatient to patient person that usually take the profit. Trading doesn't generate liquidity out of thin air but rather all those profit is just came from other person money that is on loss.
Volatility on Bitcoin is not the problem at all. People is just too sensitive on price movement and react accordingly that's why many lose while they should be in profit right now if they didn't panic sell on bottom or panic buy during the top.
