500 M XEM / 2.25 M XEM / stake = 222 stakes ...
That is exactly the same as number of The Untouched

That mean 1/10 people did not claim their xem and probably won't ever do it due to lost keys
same goes to Satoshi 2m wallter with BTC
just looks scary but this is just lost case.
Those who wanted dump XEM they did it in this 2year period arleady.
I think some of them are most likely lost but alot of them are just people holding.. I didn't touch my stake for a long long time either until the price started rising and i got a little paranoid because i didn't pay as much attention to security back when i had generated and submitted the private key as i do today. So just to be extra safe i moved my xem into another account with a private key i could be absolutely sure was safe. I'm sure a lot of people got into nem thinking as i do that this will be my one chance to make some real money and are absolutely prepared to hold at least until 1 xem = 1 usd.
