The very idea I like very much because I think that it is necessary to improve the PoW protocol, which will help make mining more profitable and attractive.
Wonder how many coins/day you think is "profitable and attractive" to be happy? For me it depends on the actual price which still is unknown. If a coin cost 0.00000015 BTC, then 1 DAC is nothing, and masternodes at 10000-50000 coins are quite affordable. But what if cost is 0.0001 BTC or even 0.01 BTC?
