The minimum capital that is required to trade effectively and compound profit is 50$; anything below that means that you are literally wasting your own calls, signals; because without a good capital; the only way to make money is if you are making over 100% profit which is not sustainable. Your profit is someone else trade capital; so i implore us to twice your trading capital.
That depends. To be honest, I first started with a capital of $10 (yes just a measly $10 because I'm poor af). Had a good call here and there while making losses but in the end, made that $10 into $100 and so on. I think it doesn't matter how much capital you have as long as you are willing to invest what you can afford to lose. It's not healthy to invest more if you're psychologically not stable in your financial position.
