thDerbit exchange was founded in 2014 out of the founders interest in digital currency (Bitcoin specifically), The exchange seem to focus majorly on futures trade using leverage to either buy long or sell short and so the exchange won't be very user friendly for the newbie because they will eventually get puzzled due the the various trade tools and features,also Fiats are not supported on the exchange which is another reason beginners shouldn't use the exchange. The exchange happens to Multilingual and so all professional traders across the globe who fully understand the leverage trading with knowledge on how to take a favourable position can understand the exchange better if their language is also included on the trading interface,it supports 100× leverages on BTC which is too risky for any beginner to try out and one of the reasons I'm not recommending it to such category of traders. The exchange claims to be the most Liquid leverage exchange but agree with them with them on that to some extent, because they might be one of the most liquidity considering the enormous trading volume.
