If the Banks where about to give a service where the people can get a LOAN via Bitcoins I guess, it would be beneficial to all of us,The Banks and The Traders.
I think with this, trading would be a lot more easier, am I wrong?
Escrows will have an easier way to get money from other individuals, and the budgets for the Campaigns will be a lot more than before.
This is impossible to happen that the bank and the bitcoin(crypto) can work together since bitcoin is digital it is hard for them to trace back which better. This way of getting collateral in having a loan on the bank is very risky for them because this crypto was very volatile and no stable value that we compare to fiat and bitcoin is a decentralized while on other hand bank is centralized, they like water and fuel that it won't work together. Let's not assume on this that surely it will not happen near in the future.
