I have 1 grid bot on Injective/Helix that I'm using without leverage, I'm 28.5% since January 1. Injective itself grew 18% in same time period, definitely won't make you super rich unless you pick tokens that grow a lot.

As far as spotting major downside, I read info about the market every day, and there is always the possibility of a black swan event, but I would argue most major dip for the current time point will be limited to about 20% to 25% on BTC/ETH at least until the ETH ETF gets approved. I will be out of the market most likely before mid-2025 as I believe it's after that time point that a major correction will happen, but I may revise this assumptions based on the information I collect every day.
