> cryptocurrency is pretty much worthless to use as currency.

I agree. I used to think that this would decrease its value, but that hasn’t happened.

There are crypto pegged to specific currencies, like USD, but the transaction fees are so high that it’s still not useful to use as currency unless I have lots of really high transaction values.

I don’t have crypto holdings but, for example, since Tether is traded on ethereum there’s a $21[0] fee for any transaction.

This may be worse than the fluctuation problem since a $21 fee on any purchases wouldn’t work for me. Comparing the fees on using a check or cash, this sucks.

I suppose this gets competitive with visa/MC, if I assume a 3% fee, around $700.
