I believe both fiat and btc are equally important in my life but if you want to save in large quantities I am more confident in btc because btc is a very important asset for the future if I only save fiat in the bank then the amount of fiat I save does not increase and I can not make it as an asset for the future.
I still need a bank for my various needs so I also choose both...
long-term savings in the bank is just a waste of time because the money we save, the value will be the same as when depositing it. but if you save in Bitcoin then the possibility of a profit of 5x-7x from the initial savings is very large.
Indeed, banks are still useful to us. Just like you did, I choose both of them. They have different purposes and people had options were to save their money. Because even though we are using digital currencies but the fact that not all establishments are accepting Bitcoin, there are times that we converted it to fiat money and we need banks for that particular situation.
But if we talk about saving, banks just only give you a few cents of interest which is too far behind when we just save in form of Bitcoin.
