As most of the countries did not legalize cryptocurrency that’s why I will choose both. Because banks are still here to make us more liquid and that is the best place for now to put your big money with less risk. I put money in bank for deposit but I treat cryptocurrency as my investment so technically I don’t want to invest all of my money because there is a big chance to lose my money. Somebody says that bank is not safe to store money because hacker/scammer stole their money.
But crypto also not safe where have huge hacker or scammers, both bank and crypto has some security problem but crypto is more prone to hackers and scammers compare to bank. Our account in bank can also hack, but it is traceable and bank do the refund while in crypto no chance it will be return. Some bank offer insurance against our deposit. Crypto have not any insurance issue. Still I do invest in crypto only a portion of my money so that in case it will gone, still I have savings left for back up purposes.
