If we talking about trading and you don't build wealth with starting capital of 50$ then you woun't do it with 1000,3000,5000 either.
That's not how it works at all.
You can profit reasonably with $50 if you're lucky not to get liquidated first but you cannot build wealth with that. You need capital to have more room to stay in the game cause trades will not always go in your favour no matter how skilled you are.
Gambling is a huge part of investing and growing wealth.
