It boils down to say the difference is just capital.
Isn't that just normal? Why would someone expect a huge gain when their capital is only small. Trading is not gambling where your 100$ could turn into a million if you're lucky. Let's not be jealous to others who are making huge gains in trading crypto because their financial capability is not the same as ours. We should just focus on how to be a profitable trader. If you are able to become one, your small capital can become huge after a year or so.
People who expect huge gains with little capital are into something very risky, it's real gambling when someone is going for x1000 and higher payouts. Getting rich quickly is something that many people want, but most of the time these tries end up badly!
Capital is important, but whether it's big or small you need to know what to do with it, you need to trade with what you have in the best way! We all know that making 5-10% with some small capital is dust, but it's a safe way, and who endure and have patience can build a nice capital!
