This is yet again demonstration how miners have total control over Bitcoin price and it's forks. Nobody can trust a system like this when few powerful people can change eveyrthing in a day.

Not as a store of value
Not as a currency
Not as anything really other than an instrument for the rich to get richer and poor to get poorer. This is same as FIAT. You have not accomplished much anything really.

Proof of Work is doomed. Proof of Stake is the future.

POS changes everything.

1. In proof of work miners can play the system forever. They can dump their BTC when it's high and buy large amounts of BHC and start mining BHC which will rise it's price as you can see from the chart in the OP and what just happened over the past couple days. Then they dump BHC at 2-3 times the price and buy back BTC when it's low and move back to mining BTC... and on and on it goes and in the future it will be even worse when there are many more Bitcoin forks.
2. In Proof of Stake you can dump your stake (your holdings) only once! Once that is done you are out of power over the system and you can't play the system forever like in proof of work.
