hi,
this might be a stupid question, but what happens to B.mine when Block halving occurs? or is it expected that this round will be over before the block halving event?
Not a stupid question! I've actually been meaning to make a post about this - thank you for asking.
The MINE daily payout is determined by the following formula:
B.MINE Hash Rate * Block Reward * 86400 * ((65535 / 2^48 )/Difficulty)Up until now, the Block Reward has been 25 BTC per block; this will be halving to 12.5 BTC per block, so the MINE payout will decrease by half!
However - this does not mean that MINE is necessarily worth half of its current value. See below for why.
At the estimated next difficulty to be set tomorrow (appx 209,538,114,804), the MINE payout per day will be just about dead on .0006 BTC. The halving is happening in about 19 days, so there will be one more difficulty change before then, but we'll just assume that difficulty is going to stay at that level for simplicity's sake.
At the current NAV/U, 0.06152229, this gives us just over 102 days of dividend at that MINE payout per day (.06152229 / .0006 = 102.53). Assuming that the difficulty stays around the same point, that gives us 102-19 days = 83 days of MINE dividend days left on the day of Halving.
At this point, the MINE payout per day will be halved, which will automatically give us double the amount of days left! Here's the math:
On the estimated halving date, the NAV/U will be .05012229. Pre-halving, this is .0512229 / .0006 = 83.53 days of MINE payouts left at .0006 per Day. With the payout being halved to .0003 per day, this give us .05012229 / .0003 = 167.08 days of MINE payouts left!
The threshhold for SELL to receive a dividend requires that there be in excess of 180 Days of Dividends at the difficulty change, so there would still need to be decrease in difficulty for that to happen.
This is why MINE isn't necessarily worth half of its current value when the halving occurs - assuming that difficulty keeps doing what it's been doing for a while now (which is NOT guaranteed), decreasing or increasing slowly, then MINE would still pay out all of the NAV/U value, albeit at a slower pace.
TL;DR: The MINE payout, since it's determined in part by the block reward, will be halved at the Halving. However, this just means that MINE will pay out at a slower rate, not that it's value is halved.
