Bots only work if they use a historical pricing model, which almost none do because you need special code to process the data volumes, even if you find one which is what I use you still have to maintain the exchange connectors, the data feeds, monitor which pairs are the most profitable, move balances between pairs, it’s a job but it you get it right fully worthwhile.

The thing with bots is this, they use a point-in-time model, mostly this can only generate breakeven (zero) profits, i’ve tested many of them. What you need is a historical data model, this needs special code to make it work, mainly due to the massive datasets, which is what I use, and it’s not easy to maintain, but the signals it provides are worth their weight in gold, people often want to use it for white label signals, rarely we ever agree on a price for it but that’s something else.

Monthly subscriptions don’t work, I use a system which is one time on an instance or the source code, which I have, it creates signals but I can adjust the coins it tracks for highest profits, like XTZ last month but Doge a few months ago.
