Setting the bot with a narrow price range and only using 20 grids so that purchases per grid are large, but this carries the risk of getting stuck, which is why I only do it with Ethereum as it is safer.
It has proven to yield a profit of 1% in 4 days, averaging a daily profit of 0.2-0.3%, so just multiply that by 365 days.
So for example, if you want to set up an Ethereum bot with $2000-3000, don't set a wide range right away; it's better to split it into 2 ranges.
So $2000-2400 and $2400-2800, each bot with 20 arithmetic grids, I use arithmetic, not geometric.
Why is 20 grids enough for Ethereum in a narrow price range? Why not use 50 grids in that range?
Because the volatility ratio of Ethereum is very high, twice the volatility of Bitcoin, so even though there are fewer grids, due to the high volatility, it still often profits in a narrow price range.
