Should I play altcoins or Bitcoin? My advice?
Players of altcoins should be especially careful, there is a big pitfall in contracts.
Pay attention to the trading fees at different times; in extreme market conditions, sometimes the fees over a few days can deduct half of your principal.
If you want to trade contracts stably, in the long run, only playing Bitcoin has the least risk. Understanding the rise and fall patterns of Bitcoin thoroughly and gradually becoming rich is the most stable shortcut.
