Bank investors have more certainty because there capital is completely safe but they give 8-10% annual profits to the investors of per year. But it is comparatively less in terms of profits.
On the other hand you will get constant profits from crypto as if you are experienced in trading then daily profits is possible. Otherwise you can get profits by investing. However crypto investment puts your capital at greater risk (main point).
I prefer profit from altcoins, the profit in the bank is very meager. I would say that when you put money in a bank expecting a profit, it is tantamount to freezing the money. Money doesn’t work well there, although of course there are more guarantees than in cryptocurrency.
