I am looking for something similar to ETH/USD on Bitmex that pays out in BTC. Thanks!
There are ALTcoins/BTC trading pairs on almost every crypto exchange, you can trade on those pairs to use your bitcoins to earn more bitcoins.
Hi I don't have dollars and I don't want dollars but I want to start trading stocks.
Here I'm confused. You need something similar to ETH/USD or you want to trade stocks? If stocks than there is currently no such thing that has established position - trust, good volume = low spreads.
If you want to trade stocks without selling BTC you can:
1- open trading account in your bank or any other broker that allows to trade stocks
2- loan USD and use BTC as collateral - you can use

3- Use USD to trade stocks and convert profit into BTC.
