Do not make banks the safest place on Earth for our assets because its not. Banks do get robbed by criminals and let us just not forget about they cyber ones too. Hackers hacked banks and got huge amounts many a times in the past. Future wont be any different. if we invest in bitcoin, then not only we will save our asset from all kind of robbers but also do beneficial investment simultaneously.
The banks or crypto needs more attention to avoid hackers. The difference we don't have to protect our account fully because that will be the job by the banks. But in the crypto, the responsibility will be in our hands so no matter what, we need to protect our account aka our wallet from the hackers, especially in the exchanges.
Either way we are not totally safe. System upgrades, and so the hackers do. But in banks the money is always insured (or it depends in the bank) lost it then compensate it. This is what I want with banking they are absolutely taking care of your money and accountable in any circumstance. Unlike with personal management all the work to avoid any problem will come from you. That is why even we have crypto for digital and speculative investment now, I still use banks for its very purpose, to protect. Also the reputation of the bank is on top priority when choosing who's gonna take care of yours.
The exchange itself is like banks in real life which can be hacked too by the hackers. So if you cannot protect your wallet, then that will be dangerous for your asset.
These banks, these exchanges has ethical hackers or people that deliberately hacks their computer and website to find any hole that can be a potential problem. Once they found out any hole that can lead to data breaching or fraudelent acts, they will upgrade their system until their ethical hackers have nothing to see anymore.
