Small evening calculation fun:
Having the wallet open for staking 24/7, which means having the computer always on drawing power, has so far given me a 0,016% return per 24 hours.
This amounts to 1,06% per year with interest of interest, less than half of normal inflation, a.k.a losing money.
So if my gains are representative this means that staking ETHD = a fool's game.
It depends on the number of your ETHD Coins
If you read the OP, the POS are designed this way
PoS Percentage: 10% Annually/0.83% Monthly
No matter how small you stake now, it will always end up at 10% Compounded POS Interest.
