price will go down and then people will sell their Bitcoin Gold to buy some more BTC and the price will go back up to $6000 or
even $7000, if Bitcoin Gold trades goes well after the fork. We will see $7000 in November and December of this year.
I think he is right. That is a good strategy. After receiving the Bitcoin Gold from fork holders start dumping Bitcoin price, then they sell their Bitcoin Gold, wait Bitcoin price dump to cheaper price as possible, then start buying again with the profit made by selling Bitcoin Gold + profit made by selling Bitcoin.
They are different currencies, but the profit of Bitcoin Gold can be converted again to the original Bitcoin, however I don't know if Bitcoin has power to reach $7000 this year yet.
