This is fully bullshit talking ever! Bitcoin world's first decentrilized digital accet, a big market cap. After the fork I usually have been heard something like this, but no strong point behind it.
How is it bullshit? Check the math and you will see this is very real and taking place like...right now.
Times without number this issue has been discussed and the final conclusion, has been that there is no way its going to happen, either because of price or mining difficulty or even the speed of transaction because by the time the impending hard fork will be happening then all the attention BCC is getting will be divided while bitcoin will remain strong.
Black Swans happen exactly when you anticipate them the least you know.
Do not fear those miners will come back mining bitcoin when they have had enough profit from mining bitcoincash. Bitcoincash will probably not kill bitcoin soon since many people still use it despite having bitcoincash.
Cope.
It is currently 75.6% more profitable to mine on the Bitcoin Cash blockchain. It is currently 136.2% more profitable to mine on the original chain.There is a possibility of chain death spiral/black swan event if and only if more than 90% of miners switch and difficulty reset doesn't happen. Now logically miners are profit driven.
1. Majority of miners would switch if and only if Bitcoin Cash block reward is more than Bitcoin block reward. Currently, $4111/$669, 6/1.
2. If not block reward then Bitcoin Cash difficulty should be 6x lower than that of Bitcoin to be profitable to mine.
3. A good number of miners mining on Bitcoin Cash would rapidly increase the difficulty. This just happened. Bitcoin is more profitable to mine now, logically miners switched.
I guess miners are making a good profit switching from one chain to another. Theoretically the chain death spiral seems possible, but practically I don't see it happening, not anytime soon or in future. For something like that to become possible, Bitcoin Cash should have a value more than that of Bitcoin, short-term pumping alone doesn't give a coin any substantial value, maybe temporary and then the crash.
