I just checked poloniex today and btcprice went don't to $5506.28 so that would be -$500 dive. Is this because of the upcoming fork? Can somebody enlighten me what could be causing this?
BTG is pump price a lot so that it is normally to dump hope not back to 4,000$ range
It won't happen. Now seems the price to be stable at around 5500 dollar. And as there will be another fork in November the demand for Bitcoin will remain high and the price rise will continue.
This remains largely unknown. The coming hard fork you refer to seems to be the most nervous moment in the last few years. Bitcoin Cash released earlier in August was nothing but a minor aberration in this regard. And when the market becomes nervous and undecided, the price usually goes down. As much as I myself want bitcoin to rise higher, to 7000$ and beyond, the deep plunge before the hard fork or soon thereafter remains a possibility which no one should discard as completely irrelevant. To put it simply, the November hard fork is not the same as the one which happened in August and led to Bitcoin Cash turning up.
As long as you hold both coins and work to separate them by tainting a transaction and moving your coins between addresses you control, its exactly the same as the fork in August, only you the user need to take some action (tainting to protect yourself). Mining power will ultimately follow the money. Users will use whichever coin offers them the most utility and traders will follow the vol.
