Modest inflation is good for an economy. It forces people to spend their money instead of it sitting in a bank account. Deflation or no inflation incentivizes people to hold the currency and not spend it which causes harm to the economy. I see people saying "maybe Bitcoin is the solution to inflation" but the reality is if we used a non inflationary currency for everyday life it would stagnate the economy. Obviously, having too much inflation is a bad thing but having no inflation or deflation is far worse. Bitcoin and non-inflationary assets should be used as a hedge but shouldn't replace inflationary currency.
