So before activation of the MN, 52680 CRS could be obtain via POW : 6*5000 + 120*189
MN collateral is 50000. So if someone would have a MN, he must be obtain about 100% of all rewards of the blocks.
Good coin.
14500 blocks with 120 coins reward per block were mined on the old blockchain. There was a transition to new algo beginning of february (from lyra2v2 to lyra2z) and new blockchain, the coins could be swapped if you requested it.. so there are enough coins for MNs.
