Bitcoin, to them, is something that has massive returns, at the cost of not being able to accurately determine when anything happens and mostly relying on dumb luck to get a good return on market movements, now anyways.
Crypto trading is often compared to gambling. Yes, luck is a heavy factor in crypto trading, but how other trading forms do not have this high luck factor? And how have we no solution that could help in predictions? Crypto investors may be very successful with their investments. I do not think, it was all luck. Because you can read the news, stay in touch with the developers, participate in community debates... That should help you predict the volatility, shouldn't it?
