Just want to notice that "secure good amount of money on your bank account" is not a safe proposition at all :) I would say it is much safer to secure yourself some bitcoins on a hardware wallet than to rely on what can be taken from you at any moment.
And if you have never lived through a fiat system crisis - certainly good for you, but take my word for it - it happens instantly, you just all of a sudden have numbers in a bank account that mean nothing and can buy 1/100th of what they could yesterday.
So yes, secure your crypto! And don't trust no bank especially if you quit your job.
