Also I would suggest you increase the inflation to 3-5% a year. This much of inflation is good.
Stability in prices -- Cryptocurrencies are not commodities. It's designed to be spent and a medium to receive payments from. If a cryptocurrency is not that, it's basically a pump and dump scheme.
Actually if you see for a fair cryptocurrency which is not seen as an investment, there should be a little bit inflation, cause that way people will not hold on to it like investment; instead they'll use it to buy investments like shares and gold -- which is something to be seen as an investment.
Even real currency have an inflation problem and it's usually more than 0.5%. Actually it depends on the country. But do people have problem with that?
If they did not like their current currency, they always had options. They whould've chosen fossil fuels anytime (who's value will always increase); the reason why they didn't is cause the inflation of national currency is negligible for them cause they use the national currency to spend, rather than invest and hold.
