~
on my list is Binance, Bitmex and Okex. Any thoughts?
Binance is good as it has many features and even lets you play games in their platform. Though some features requires KYC, I don't think it would be an issue as you've said that you wanted to take higher risks, also, Binance have a lot of users/traders that are active hence it's volume was fair enough. This isn't to promote Binance but I think it's the best if you would pursue daily crypto trading and focus in it.
But if you really love to have a long term (that you can still be using in the future) trading, better reconsider trying Stock Trading or Forex Trading. Most traders there trades for years and wealth is mostly growing (unless you aren't that good enough)
