I have been playing with Bollinger Bands recently, and they seem to be doing okay for me. If the market slowly drops then it doesn't do much, but if there is a drop outside of the norm then it buys the crypto as I am hoping for a (positive) market correction.
My bot again sells for a 3% profit - but you can play with higher/lower figures.
Out of three bots (running on ALGO, ATOM, and HARD) over the last week I have made 20% ; 11%, and -10% returns. Overall a gain. Yes, it didn't work on HARD and I'm waiting for the price to still slowly rise. But I don't mind hodl'ing either as at some point I am sure that it will rise again above my buying price (and I just have to be patient). And overall it is a net profit.
Saying that, please do not jump in until you have done your research (as @claudio83 mentions above) and HODL until you are ready. I am only experimenting with 20 USDT per "bot" so I can afford to loose it all. Until I am sure that long term it is a good idea, I am only investing what I can afford to loose.
