Remember: "Prediction is difficult, especially about the future".
1.5 per month is based on real data of the last 30 days of mining, not based on assumptions and estimations, so no I am not smoking.
real data based on the last 30 days of mining I can tell you for a FACT that each be makes .002 per day
Impossible, even as of today each one makes about 0.003 per day (24 Hour Earnings 0.02851029).
I will change the description to make it clearer.
Even at current rate, 10 keys for 1.99 BTC is still the best price you can find, to take or to leave.
