It’s funny, because the inflation of crypto comes not from the increase in the supply of individual coins (that’s controlled mathematically) but by increasing the number of cryptocurrencies themselves.
Can’t say for the memecoins and NFTs — but when it goes from just bitcoin to hundreds of different competitive legit coins, that does seem like inflation of money supply.
That is a perverse use of "inflation" unless a holder of BTC or ETH were somehow forced to spend some of his BTC or ETH on every new cryptocurrency -- or it happened automatically, and for the holder to prevent it from happening was risky or tedious.
