Boahhhh this sounds stressfull indeed with the amount of options where you can make a fak-up anywhere.
Honestly I think slippage in trading in these giants of exchanges are not that bad (or you secretely are the whale which is the market mover), and all of these trades also cost something.
But uhhh...are you happy with Bittrex as a cash out cow? I am still looking for the best one as I haven't really done this as yet
It wasn't fun.
Bittrex works fine though.
