Are you concerned by other commenters who mention that once they were successful the exchange moved in to either stop them or extract a fee?
What lowers my concerns is that such issues might come once the bot is profitable, and by then I might have found other ways to raise capital (I'm doing a trading bot as a way to raise capital to create an AI research lab). Being able to setup a profitable crypto trader is a good thing to add on a resume or for personal branding even if I shut it down at some point. I'll be in a very different position by this point so it's a bit premature to be concerned about that now, although it's still somewhat of a concern.
On the positive side, I hope this scares the competition away.
