With respect this is very incomplete advice. This will depend entirely on the actual fluctuations in the particular crypto you're investing in. If the crypto has very small but frequent price fluctuations, then a smaller grid profit will probably work OK. But for currencies with fewer, but larger, fluctuations, this would not work at all. I generally run two bots per crypto with a very limited range. For example, on ETH, I've currently got a bot with a range of $3100-$3800 and 35 grids with a profit margin of only 0.31-0.38% per grid. I've got a second bot running the same range but only 20 grids. One basically handles the huge price fluctuations during the day (ETH is most active on Pionex and Binance during US stock-trading hours), and the other handles the small price fluctuations at night. This configuration will suite me until the rally to the next Fibonacci level or until the next downturn to the previous Fibonacci level. None of this will be relevant in a week or two. Your bot strategies must change frequently in order to remain profitable during such volatility. It also depends on how much you're actually investing - if you're only putting $500 into the bot then you're probably wasting your time with 0.5% per grid in most currencies.
