Inflation isn't inherently bad: an overheated economy, which is the result of inflation, is. This is basically where we are right now. Had the fed not gotten cold feet when they halted the rate increases we'd be in a far better position right now (sans a few banks with bad balance sheets.)

The fiat currency discussion gets murky quickly as most everything's value is relative and derived from something else's value. Crypto is no different and arguably has its own set of issues.

Ultimately regardless of the currency we as a world introduced a ton of what should have been temporary wealth during the COVID period into the markets to save lives and businesses. That money needs to go away to restore balance to the economies. This means a negative inflation rate, or put differently, deflation.
