They forgot to realize that if they are just consistent on trading and to learn a lot of things that can help them on their trade for there are probabilities that the small amount they use will became huge especially if they have good learnings and good decision making towards the coins they are trading. Somehow its really hard to gain from trading since everything is unpredictable there, But if they are consistent and willing to learn from multiple sources then maybe the result will came different and the small amount they use will became more bigger due to the learnings they get about trading.
There is no guarantee that by bringing large capital we can get big profits, because when we experience losses, the losses we will incur will be greater than if we brought small capital.
What's difficult is being consistent, because we can't just get consistency. We have to learn more to make the trades we make run well and also generate consistent profits.
