What rate of return do you need to meet your cash advance interest from the credit cards?
22%? Cash advance rates are usually higher than regular credit card interest. Yikes.

Sure you could pay those off over the next couple of months but you are still paying interest for all of the months you don't pay it off.

Don't get me wrong. I'm not saying bitcoin or any investment is a bad idea. I'm saying that the risk you are taking is very high.

If anything, take money out of your home with a low rate and "invest it".

And I'm not this older guy who feels extreme need to be conservative. I'm fully invested and looking for long term rates of returns.
