Have you claimed any of your steem since joining steemit? Then you're using a cryptocurrency now, as it fills all but one of your criteria, and I'd argue the one it doesn't fill isn't necessary.
decentralized, anonymous, physical(off the grid), accepted in any culture/race as store of value, medium of exchange
It's decentralized, it's anonymous, it isn't physical, it's accepted by any culture/race as a store of value, and it's a medium of exchange.
Why does a currency need to be physical?
it depends on the grid. it is not accepted by all races/cultures. it is unlimited....
as to the physical aspect, i think you are smart enough to figure it out yourself. do you know the what the original USD dollar says ? silver certificate, redeemable into silver bullion? why is it so important? try to figure it out yourself.
steem is not anonymous at all. i can see anybody's wallet! and you call it anoymous? do you know how much silver i hold? but you know how little steem i have in my wallet.
There are people from all over the planet on this platform who would gladly take steem if I offered to send it to them.
I don't care what the USD says, it was created before computers even existed. Outdated.
I know how much steem you have, but I have no idea who you are.
