One more little contribution: i got $ 50 Vultr credit for free and setup a simple exchange, look:
kashmircex .tk (i cannot post it without space so remove it of course)

You can trade, deposit & withdraw even without email activation, but i recommend to set 2-factor-auth.

I have enough funds to run it for about 2-3 weeks so far. Lets test it. If you will find any bugs you can send me a message through the ticket system
