If you can't consistently turn 0.2 SOL into 1 SOL a day, how can you expect to turn 2 SOL into 10 SOL a day consistently?
The percentage gain is still the same, regardless of how big your port is. In this case, 5X.
In my opinion, you should focus more on percentages and X's rather than monetary gains, (unless you're scalping or swing trading with size.)
If you're a low port trader thinking, "If I had 100 SOL to trade with, it'd be so much easier." That's not necessarily true. If you can't manage a small port, having a bigger one won't magically fix your execution or discipline.
Learn to trade well with what you have before worrying about how much you have.
