My employer won't pay me in cash. I have no problem with my bank. It is USAA.
It has no shareholders and all profits are returned to members so there isn't any incentive to fuck over depositors or borrowers.
Lastly the price of Bitcoin is related to utility and if the only way into the economy is to go meet a complete stranger with a bag of cash the utility of Bitcoin suffers and thus so does it's price. Honestly my life is busy and complicated enough to start tilting at exchange windmills.
Just wondering do you also keep all your retirement assets in a safe in your home because you fire your broker?
Do you expect all forex traders to just keep big bags of cash they hand back and forth with other traders holding bags of cash in their respective currencies?
