I personally prefer whale club over bitmex, for one, the chatbox pays you to contribute and trolls/spammers aren't tolerated. Built in News and a calendar for upcomming news related to fiats/stocks. Can also Leverage cryptos.

I wrote an article on it. If you like bitmex, you'll like whaleclub. I, like you, just play around with 50 bucks here and there lol. Then cash out when I'm done. Or if I lost it, then yeah.
I will have to look into them thanks!
