It's no longer news that there is no merit still holding your money in Fiat currencies or depositing them in the bank for long term saving because when you are holding your money in any Fiat currencies that money is not actually appropriating rather it's losing value over time so the best thing to do is to put it into an investment that will bring return to you in value.
Everything is increasing in value hence if you keep storing that your money. It won't grow and that's how you'll be short of money always because the world had appreciated in things while the value of your money remind the same. You go broker holding money but increase in wealth when you're investing your money into different things.
The things mightn't be cryptocurrency but provided you're making a profit then continue investing because you need money to live a comfortable life everywhere. Fiats always depreciate while investments appreciate your money. When you can't look for opportunities to invest then you can put your money into things like Bitcoin that doesn't need much stress to make money.
