I just checked poloniex today and btcprice went don't to $5506.28 so that would be -$500 dive.
When you refer to the price of bitcoin from poloniex it could be because of many sell orders from traders or a time difference that was awaiting a correction to catch up with the market price.
Is this because of the upcoming fork? Can somebody enlighten me what could be causing this?
Usually when there is an airdrop as a result of a fork, we should expect a surge in price and not a dip...so this could not be the reason.
