I believe that is wrong. If you keep your money as cash or in a bank deposit then you lose several percents every year because Western governments maintain a certain inflation rate. But inflation is basically stealing from everyone who has cash or bank deposits. You had 100 dollars and next year they become equivalent to 98 dollars.
Cryptocurrency is different. No government is able to steal your Bitcoins by printing some more colored paper.
Yes today there are issues with volatility, but conceptually cryptocurrency is better than fiat money for the reason written above.
But if you like getting robbed every year then of course continue using fiat money.
