Have you ever mined Ruby? Each coin takes quite a bit of mining to get, to the point that having over 100 is equiv to having thousands of Blackcoins. Ruby is absolutely worthless in comparison to Blackcoin.
Yeah I was there at launch for their fucking scam giving premine to certain pools, mined it for half hour before switching back to Blackcoin.
This is my point though, the coin is worthless it shouldn't matter how long it takes to mine for however many coins people should not be buying it at that much
