Depends what you want to buy. Asset prices (property, stocks, bonds) are deflating right now, so your purchasing power is actually increasing in regards to those investments.
Things to buy with currencies experiencing inflation - hard assets with steady or increasing demand will probably do well over the next decade, but even those still have downside market risk as recession starts to bite, central banks keep tightening and all assets get repriced lower - likely lower than than current inflation.
With cash the only downside risk is persistent inflation - holding cash is ok for some time, but not forever. The value will get eaten away with inflation over time.
This is assuming you have available access to financial markets and US dollars. If you don't, I can see how stablecoins like USDC become attractive, perhaps even crypto like bitcoin and ethereum. Just stay away from the dodgy stuff - if it looks too good to be true, it probably is.
