currently , due to wider acceptance and being the normal, id go with banks though crypto is much safer with faster transactions and in some cases, anonymity. in the nearest future when cryptocurrency gets wider acceptance, i'd definitely prefer keeping money in crypto than using banks. crypto was built to combat the fraudulent and backward financial system that's why they are kicking against it so much.
Sounds fair enough but how about scams in cryptos or if you lose your key? Such a tricky world of currencies we have right? It sometimes confuses me to be honest. I've worked in a bank for over a decade and I've seen how tight were the security measures yet fraud still kept happening. On the other hand, Cryptocurrencies had also seen history of cyber crimes. It's really damn if you do, damn if you don't kind of world.
