Among crypto derivatives exchanges Bybit is now in third place by volume. In March they significantly increased their volumes and added trading with perpetual contracts on BTCUSDT. They also have great contests for traders. I recommend to try it. This exchange will become more popular in the near future, it is strange that not many people have heard about it.
The exchange has convenient tools, charts with TradingView, the control panel can be customized. Overloads and downtime was not observed at all. It is also one of the few cryptocurrency platforms that is protected from market manipulation, hacking, downtime and "crashes". All this allows me to look confidently into the future and concentrate on the trading process.
I am sure that soon Bybit will become a leader among cryptocurrency derivatives exchanges.
