Inflation devalues the worth of every hodler. Gold has inflation and it devalues Gold with about 1.5% a year. Its still valuable because fiat inflation is much much bigger than that. Same with houses that are build new in addition to the existing ones.

That is why Bitcoin being limited to 21 Million is The Greates Money of them all.

Selfish mining attacks succeeded with Monero 2 times, not with Bitcoin because probably there are differences ASIC vs CPU, incentives and so on.

Inflation in Monero devalues the worth of any Monero holder. Inflation is always theft!
