I don't have a 'money market account' for a good reason.
The US dollar is backed by the full faith and credit of the government of the world's largest economy. For now, anyway.
Bitcoin and rest of the crypto currency copycats are backed by... What?
bitcoins are limited currency that's what. federal reserve notes are backed by full Faith and credit of The People and are elastic to the people, who make new loans but also the government who make new loans with no actual market demand......they are your "fiduciary agent" in that regard....
weather you still get a paper check or use direct deposits signature card, you are endorsing the federal reserve system, quite literally. bonding your substance with every deposit to the reserve system....
even folks like yourself who are all cash....which is almost non existent anymore, you still fall under the label of "reserve agent" by physically holding the notes with no recorded demand for redemption.
that's why you sign the back of your check, something that is not required if you are at the bank the check is drawn apon.
if you are cashing a payroll check drawn on BofA inside a BofA then all that's needed is an Id check, no endorsement.....if they try and charge a service fee on the instrument for not having an account then they have a bounced check, as it's an obligation to pay the face amount.
Americans need to learn how banking works, you should start with....
"endorsement"
because the Fed is the final clearinghouse for all checks, electronic "checks" included.
