The son of Donald Trump, Eric Trump, also the executive vice of the Trump Organization said banks can extinct in 10 years if they do not watch what is coming. I think what he meant is that if banks do not support cryptocurrencies.
He's quite smart but Bank if not internationally connected have nothing to fear,
They also are very different to crypto, their function in society is system endemic.
Crypto is not. Crypto can disappear over night and hardy any harm is done.
But people's fantasy is living without banks would be a better world. No more grocery stores to buy from.
