In 2019, miners have been revving up their ASIC to make use of the last Bitcoin block rewards before the halving in May 2020. The extremely high mining activity also meant that during some time periods, the network blocks arrived less than 10 minutes apart.
Bitcoin Blocks Produced Ahead of Schedule
On average, this meant miners distributed an extra 50 BTC per day. Most of the extra rewards went to the four largest mining pools, based on CoinDance statistics.
The Bitcoin network does not have an agile, on-demand difficulty recalculation. Instead, the difficulty of finding a block is recalculated every two weeks. Miners have also managed to vary their output, so that during some time periods the difficulty would be recalculated downward.
Right after the more favorable difficulty conditions, miners boosted their activity, setting a series of records by producing more than 110 quintillion hashes per second. The highly active mining is so far unaffected by Bitcoin price fluctuations, and peak activity happened on days when BTC market prices tanked.
BTC is not the only coin being mined ahead of schedule. Due to the still high difficulty, the Bitcoin blockchain is not really strip-mined into oblivion. By mining this actively, pools are actually bringing the halving date closer.
Forked Coins Also Mined Faster
But networks like Bitcoin Cash (BCH) and Bitcoin SV (BSV) may see their halving arrive even faster. These networks habitually produce much faster blocks, sometimes coming each minute. The Bitcoin Cash network has already generated 18,134,125 coins. At that pace, the BCH reward halving will arrive in just 133 days, while the BTC reward will drop to 6.25 BTC in 172 days,
As for BSV, there are just 15 coins more in comparison to BTC. The BSV blockchain remains a bit slower,…
