OKCoin and BitMEX doesn't offer trading to US traders which is what I was looking for.
I feel like these are the best exchanges to trade futures and options so it's probably
best to create a subsidiary in a foreign country in order to take advantage of the
opportunity.

The other exchanges mentioned don't allow automated trading, which is what I
concentrate on. 

I'll definitely bookmark it, but I'm looking for an exchange with more liquidity. I hope your
website grows, and it should because it's virtually impossible to find an exchange to trade
options or futures in the US. I'm sure the government will come after you as well when you
get big enough lol

Are there any reliable(keyword) exchanges that allow you to trade futures and
options if you're in the US? OKCoin and BitMex have the liquidity, but they've banned
the US. I might just buy a forwarding address in the UK to get around this if I can't
find a US alternative. Any suggestions?
