ehi guys!
first thanks for the amazing thread

right know i'm using gunbot with different exchanges (btc based / eth based / usd based) simulating strategies with mathlab and it's working fine, nothing exceptional with this market..
i've just tried crypto-php with MH and i was surprised by the results!! i'm using 5% profit as target and i get lots of trades! next step will be to test ARBI as it looks like one of the best option you propose, i'll let you know!
about vps i'm using contabo, nothing incredible but really cheap!
cheers!
