The crypto investment sector is different from the agricultural sector, I don't think that crypto investment can stop anybody from engaging in any other work, like agriculture, it's an investment that you can engage in and still do your regular day job. Except perhaps crypto trading that requires special skills like learning fundamental and technical analysis, the investment part is basically to hodle and monitor the market trends to know when to sale and buy.

I think that why the younger generation might be more inclined in crypto and other internet related jobs is because they don't want to get their hands dirty, they prefer a job that doesn't require manual labor, just technical skills that they can stay in a comfortable place and do, unlike the food sector where they need to engage in manual labor to get their job done. Another reason could be as earlier mentioned, crypto investment gives them chance to engage in other things including agriculture.
