They did not create bitcoin out of anger; it was just that sometimes we need to use new technologies, and that is why our mentor Satoshi Nakamoto came up with this technology, which is bitcoin. Other cryptocurrencies now follow in the footsteps of bitcoin. It was created to give us financial freedom by giving us access to our funds without any third-party fees. I think bitcoin fees only get charged when the mempool is congested, but on a normal basis, it is normal; it is not much when you want to do a transaction, so it is still okay, and bitcoin is not trying to copy banks; it's just that that's how it works.
