Looks like the alt-media are starting to use the "F"-word in regards to Bitcoin Core vs. Bitcoin Cash

Due to the economic and technical nature of Bitcoin and its blockchain its more than possible that the new fork, widely being called Bitcoin Cash, BCH or BCC, will overtake its rival fork now commonly called Bitcoin Core. The effect of this "flippening" could be nothing short of disastrous for those holding Bitcoin Core.

Since the recent Bitcoin hard fork we now have two Bitcoins: Core (the original) and Cash. When the fork happened those holding BTC (in their own wallets) were also able to claim an equal amount of BCC (for free). This created a huge supply of BCC. However, many or most people rarely keep their BTC in their wallets, preferring instead to keep them in online exchange accounts. As a result, even though the exchanges warned people they needed to withdraw their BTC to claim the BCC, most of those people will never get that BCC. Instead it became a windfall for the exchanges.

When the fork occurred the Cash chain inherited the then current difficulty factor of the original. When operating nominally both chains should have new blocks discovered by miners about every 10 minutes. Because at the outset the mining effort for Cash was only a small fraction of the Core's. the rate new blocks were found (and therefore the transaction capacity) initially was hobbled. This was anticipated and the developers included a means to detect when the hashing power on this Cash chain was too low and to quickly adjust, in 20% increments, the difficulty factor.

By far the main driver for miners is revenue. In general they will go to whatever blockchain they earn the most. Analysis of the hash power being expended on both chains versus the difficulties and value of each coin showed that the two were converging insofar as mining profitability. There is also an anomalous aspect to the sources of the BCC mining power. Unlike that of BTC, where most of the hashing power is associated with known large mining cartels, the majority of BCC mining is by unknown parties.There has been significant variation of mining power over relatively short intervals on both blockchains. The timing of this variation very much indicates that the miners were attempting to beneficially manipulate both the value of BCC vs. BTC and quickly decrease the mining effort for BCC.

  • Since 11 August Hash Power on the BCH chain has increased daily.
  • Hash power on BTC chain on the other hand fluctuates from day to day, by up to 1000 PH and the mempool continues to grow.

The table above are snapshots taken at a point in time each day. Their individual states can be monitored in real time here*.  Scroll down to the hash rate. BTC hash rate is down to 4853 PH. This is more than 2000 PH below the table above and the mempool has now exceeded 65MB. A Death Chain Spiral may have set in but is being "managed".

This large fluctuation of BTC hash rate could be the miners preventing difficulty from adjusting downwards, and at the same time growing the mempool. It is also possible that with over 1000 blocks to the next difficulty recalculation, we may not see another difficulty adjustment on BTC anytime soon.

It is uncanny that we see very little discussion and debate at the very top. It is as though the NYA agreement have settled everything. However make no mistake. What seem calm belies what is happening in the background. Like a duck on the water paddling furiously underneath.

Over at r/bitcoin talk seems to center around price and technology. Nothing about any negativity, usability or the growing mempool. Censorship of robust discussions is just downright deceitful. Especially if it is the de facto forum. It must quit being a propaganda organ. There will be consequences.

The people around Segwit may be frantically on the phone, fax and email arguing and pleading with the miners. They can see the writing on the wall. Only 124 blocks were found in the last 24 hours. Block time have increased to 11 minutes and the mempool is in excess of 70MB. It is "too little too late". For many of the miners "Revenge is a dish best eaten cold".
