Bitcoin is not as secure as banks are, not because of the security but because of the fluctuations, if you save your money in a bank they would be the same even after years but if you save them in bitcoin there is a chance that they might grow or they also might drop their value because bitcoins grows and it drops as well sometimes.
The fiat you put in the bank will be the same in amount after a few years, but lower in value. One thing is for sure when you put your money in the bank, it will lose its value due to inflation. And bitcoin on the other hand can become higher or lower in value. At least it have a chance to grow in value. But in banks, it will just diminish in value.
