Please tell me where i said that a bitmex api key alone can act as a private key of the bitmex's wallet.
Not interested in playing word games with you. You keep shifting the goal posts, and again, we're very familiar with this kind of behavior.
This guy summed up the problem with what you are offering more-or-less perfectly:
I have not encountered 1 bot, in the world of crypto trading, that had a proven track record of consistent profitability and was also on sale for the retail public's benefit. If there was any significant alpha factor, the owner of such a bot would be extremely cautious about not compromising that edge by sharing it with the public. You would be the first of your kind in this case, which is highly doubtful, but I'm sure the intelligent traders & investors can decide for themselves.
I understand you are not selling the bot. No need to nitpick that point. But the problem remains: if your bot is consistently profitable enough to offer consistent returns of this-or-that a month, why share it with the public? Why not just compound your own profits and not run the risk of having somebody figure out what your bot is up to?
Furthermore, one point of clarification I'd like is, how do your customers benefit from your account having "market maker" privileges if their accounts do not? A few trades you made that appeared to be a loss may have still been profitable to you thanks to such privileges, but would still be a loss to them. I'm just trying to understand how you reconcile this difference.
