no sense to buy if [add something here]
Hahahaha, no sense to buy. If and but and then some more buts and ifs... southern mathematics.
you pay those xcn the cost of your electricity which is far lower than buying on market with bitcoin
Miner is always late. Always.
well almost everyone here have 10 rig right? everyone here already roi'ed with his rig, minus newcomers which doesn't matter
i'll make an example, when xcn was at 20 satoshi, with 10 rig you could have mined 1 million a day, instead of buying the same amount for 0.2 btc or $500
i would have paid only 1 day of electricity to mine that 1 million...which is basically free coins
