BTC : " Where should I go? What should I do?"
BCH : " Frankly my dear, I don't give a damm "
This big block/small block saga like the story above, started well. So what happened? And as the question begs. Where should BTC go? What can BTC do?
Sadly, for BTC there are no good outcomes. The Chain Death Spiral has set in and it can only have one ending. The BTC chain will come to a grinding halt, because the little hashing that is left, will not be enough to take it past the next difficulty adjustment, if it makes it past the one coming up.
At the very core,(pun intended) the real difference between BCH and BTC is that people embracing BCH believe in the protocol while people embracing BTC believe in the development team. Because the protocol was held hostage by the development team, this current state of affair arose. Never again should we allow, or even make it possible for any faction, not even miners, hold the protocol hostage.
We are now watching the end game play out. The value of BTC is crumbling. The parties holding the price up will soon give up completely. It is futile, When the chain in question is impossible to use, it does not have a value. Already 38.95% of the hashrate have migrated to BCH and they are never going back, despite wishful assurance that they will, arguably to chase better profits. In reality, for a large majority of miners, the bitter experience of the past have been too painful. In addition it also does not make any sense to be mining on both chains.
A miner now earns 83% less, mining on the BTC chain. In addition he wont be able to cash out for at least 2 days and by then the prices could have fallen further. No commercial miner can absorb these losses for long, no matter how strongly he supports the losing chain. His losses are uncapped, unknown and uncontrollable. Contrast this situation to that of the initial early BCH miner. He could allocate and budget for a cash burn until the project succeeds. His losses are capped, known and controllable.
BTC price may never recover. It will slide downwards with decreasing usability, The BTC chain may never be profitable to mine on again. On the other hand the price of BCH will trend upwards with increasing hashrate migration.
The End
Soon, BCH block height will surpass BCT to become the longest chain. By then it may even have the higher amount of hashing power. The BTC chain will just grind to a halt. It may not even see the next difficulty adjustment. The core team can move their agenda to Litecoin. The natural order and balance of the crypto universe will be restored.
