Blockchain didnt get robbed, the exchange ( s ) got robbed. Also the price of Bitcoin didnt drop because of this, NEM dropped and right now already recovered. Crypto is indeed safe because it has never been hacked, Mt. Gox = an exchange, Coincheck = an exchange and due to bad security they got hacked. This is something different than Blockchain.
I'm not sure what you are getting at, as I never mentioned blockchain. Bank / credit card = equivalent of exchange in my eyes.
