This generation is actually looking for were to invest their money and earn returns.The banks are not helping here because even if you save your money in the bank it amounts to nothing because the interest rate is so low.
I am only going to share my own answer based on my surroundings, there is no data to back this up OP, the young men you mentioned are still very new to crypto and Bitcoin, most of them joined after 2021, like I've said this is my own surroundings, I've been accepting Bitcoin as payment for a long time now and since this bull market starts it has slow down, everyone want to hold their Bitcoin and not spwnd it.
With the little youths around me they don't care about holding Bitcoin, they want to sell and make some quick money, they lack patience too, many of them turned to Internet fraud for quick cash flow, it's very rampant over here, I guess parents have a lot of work to do, they raised their kids into grown man pressuring them to bring money home and these youths don't want to wait.
