Some investors (especially the newbies) wants to have an instant profit. Just like if you invest in meme coins or those coins who are currently hype and supported by a famous influencer. It can really skyrocket in snap and even its too risky to invest in such coins, they still do it without hesitation. Greed is the problem and lack of knowledge. Some altcoins are good to invest in but its often ideal to hold for short term, if you want to go long term then Bitcoin is still the best option.
Unfortunately that came out of actual profits. I mean if you made some good returns in that short period of time, and promoted it on twitter then you would become the problem for it. Try to remember all those people that invested into memecoins and then you will realize that it is definitely something that won't be beneficial for you at all. It is going to be something that will be a bit of a problem.
At the end of the day, those "influencers" that made so much money and all those tweets about how they bought some shitcoin and got rich caused many new people to join and lose money. You can't recreate the same thing, but they tried, and since those shitcoins were already higher than what it should be, it dropped to where it suppose to be and that caused people to lose money.
