It's okay if he won't get rich with his technique. The key here is about being consistent with his investments and the set of choices. Consistency plus having a good choice of investments are going to make him rich someday. Right now, if someone doesn't have much money to invest, it's okay. You'll get there someday that you'll be having bags of investments but don't stop investing and do it while you can right now with the little that you have.
Being consistent doesn't really help if you are choosing wrong coins. Like imho op did. If the lack of knowledge for example would be the basis he works on consistency could be a problem. Like people who are being rugged and understand it years after others did.
