It seems they underestimate how does the trading works, it seems you share here we might think its a crypto, we know how does the market volatile and people getting trade much with the market but if you are totally newbie could be a struggle into you if you don't know whats the next move if the market is not going into an uptrend, like recently the market goes into sideways if you are an inexperience newbie possible you make a position right there hoping to get pump with the use of the resistance and support but the market goes into other way because you don't have an idea there's a confirmation yet instead you missout the possible gains due to an early entry.
I do not think they would even take advantage of pumps, because newbies thing it can sustain for far too long than it really can, and they make mistakes because of it. The reality is that you can't get rich doing this in a month or whatever they are looking for, too many people out there who are in financial trouble, looking for a magic wand that will make them pay all their debt, and get rid of all their problems. That just can't happen, it is not in crypto at least I can tell that much.
You CAN get rich, over long period of time, by doing good trading, that still exists, but it takes many many years and not something that can be done quickly. And by the time you are doing it, you are not going to be a newbie anyways.
