Are you looking to margin trade Bitcoin and other cryptos? Looking for a more reliable platform compared to Bitmex? Here are some of my favourite margin trading platforms for crypto.
FTX is my current platform of choice for leveraged crypto trading. In my opinion it's the best alternative to Bitmex.
FTX is unique in that it offers a number of unique trading products alongside its crypto offerings. For example you can trade a presidential future. They also offer contracts on a huge range of alt-coins, something that can't really be found on many other platforms. I've found it very useful for shorting scammy coins like BitcoinSV.
