A 100% no.
There is no reason for me to take a loan and invest in something volatile. I never know what will happen in the future. Meanwhile, I will have to pay the debt no matter what my financial situation is. I know Bitcoin grows more, and my investment can become 2x or even more after a few years, but I won't gamble by taking a loan from the bank. It's just absurd. No one should take a loan to invest in Bitcoin or other cryptocurrency knowing it's too volatile.

If you have your money already, consider buying some Bitcoin and holding it for a few years if you want. But there is no reason why you would take a loan from bank and invest in something which is considered as risky investment.
