I think you just buy extra when they fall and sell them when they go up. With esg you can make a few k each couple of weeks when they fall to 16 or 17 cents and then hit 20 or 21 cents.
Each 100k of shares you buy will net you three of four k.
But keep a certain amount so you don't miss the boat when they go up.
eg buy 200,000 shares and trade 100,000.
