Nothing is plagued by zero inflation. Bitcoin is just relatively better not zero free.
Volatility despite being a strength in Bitcoin destroys stability as a store of value especially in the short term.
What OL needs to realize is that, terms can apply differently.
Inflation does to fiat what volatility does to Bitcoin. Understandably, volatility could apply either on the positive or negative side and that’s where there is a major difference. It might be bullish and continues to go sup there by adding value to whatever you are holding or it might dump and devalue your holdings.
Inflation devalues fiat and so does volatility towards the negative, it’s just way better than you have in fiat that’s all.
