> every currency transaction creates this risk.

This is a disingenuous straw man and a desperate attempt to brush away Bitcoin's failure as currency. The OP explicitly referred to cryptocurrencies' inherent high volatility, and volatility is not a mere transaction risk. Seeing your debt explode, because you either borrowed or deferred payments, due to cryotocurrency volatility is not a transaction risk. It's simply the fact that cryptocurrency fails as being money.
