BTCB2 Cost of Coins

What a Blake2b rental actually mints once the difficulty retarget lands and the network keeps growing — instead of the number you get by extrapolating today's block rate.

How it works. Every hour the model adds your hash to the network, mints blocks at the rate the current difficulty and network hash imply, and pays you your share of the reward. When the epoch reaches 2016 blocks, difficulty is re-set to what 10-minute blocks would need (capped at ×4, exactly as Bitcoin does). The current epoch is on pace for a near-cap adjustment, so a rental that spans it mints most of its coins before the retarget and very few after. Prices are per day of hash; pool fees and stale shares are ignored. Times are shown in your local timezone.
