Hi Ethan, while delta seems like a good exchange, please note that it is a centralised exchange. You do not 100% control the funds you keep there. Ideally, I would recommend to trade on exchanges that have transparent custody like Blockchain Board of Derivatives. This is also a futures exchange with leverage upto 50x. The best part is zero fee trading and transparent custody. Also, you could trade altcoins with leverage upto 25x.
Check it out for yourself! Cheers!
