Although, no doubt because there are all possibilities for such to happened only if they get involved in with altcoin that are more of pump/dump, when they are lucky they could get pumped to cash out good profits from their investments and only those who have been in the cryptocurrencies space can actually achieved such quicker profits.
You just rounded up the discussion with the truth by saying, “Only those who have been in the cryptocurrency space can actually achieve such quicker profit.” If not, how would a newbie in crypto even know which altcoin to invest in to get a quick return?
Let’s be honest, we all know crypto is not a “try your luck” scheme where you just throw your money into an alt coin and it suddenly pumps overnight, making you rich. That narrative is not only misleading, but it’s also dangerous.
It seems you don't really get what he was trying to say , he was talking about alt coins that is pump/dump projects.There are individuals who have had different experiences with altcoin, there are those who has been lucky with it,also there are majority who was not so lucky. The lucky are those who invested when the project was still going up lucky for,they were able to sell it off before it dumps also there are majority who has lost there money because the project dump some even turn to dust and they couldn't get back there capital . However this not the same with bitcoin, with bitcoin this kind of scenario is not possible because bitcoin has proven it's worth over the years as a potential coin and also as a store of value.
