Global bank strategy can also be use to loan individual Bitcoin, laws and regulation will be in place to ensure both parties interest is taken into consideration, escrow can be use and a percentage will be use as interest for the borrower, this will be base on tine of repayment.
So, why the involvement of banks again in cryptocurrency loan when this can be carried out easily in a peer to peer loan group. If you go to the loan section of this forum, you will see how many people are requesting for loan and being grated loan amongst themselves with the necessary collateral being giving to ensure that the loan has been paid, and since I have been visiting there, I have never seen any one that has loaned complain of being duped or not being paid because everything is well spelt out there.
Banks always want to out their hand in everything and if they still out their hand in cryptocurrency load also, they will operate it still the same way they have been operating their traditional loan when they give it out.
