The main problem in my opinion is a small profit.
Small profit isn't the main problem but rather what we should expect as small capital comes with small profit. And with small capital we can lessen the risk and of course we can loss with just small and actually in investing we should start with this. Start small and just add some to it when you already profited, don't take risk in bigger investment when you know your capabilities and tolerance is just limited.
- Yes, small profits are not a problem, that is fair exchange, small capital will be small profits, many people never accept this, they always live in greed and dissatisfaction, until the end, they end up in a loss that they never thought of. And the biggest challenge that I think is that we will be limited in choosing goals and optimizing profits, we do not have much capital, we need to be more careful, more calculating, rather than reckless, so as you say, using small capital is suitable for newbies, helping them to recognize their scope and abilities
