Lower value coins double quicker and easier though. If I invested in bitcoin today to double my investment, bitcoin would have to hit close to 150000 Australian dollars. I receive crypto from brave browser and I threw some of it into dogecoin and my investment has already at least doubled. I actually messed up by deciding the pump was done and diversifying when if I had kept it in there, my small initial investment would now be worth about $800. Meanwhile the tiny bit I have in bitcoin isn't going to ever turn into anything substantial (and as soon as bitcoin goes up a smidge I intend to put it into a small coin again) while multiple small coins I hold have each doubled in value. If they crash nothing is lost because it was just my ad revenue but without more to invest to begin with, bitcoin isn't worth investing in at this point. It's only useful for people who can put a lot in.
