r u sure that there will be a "new" coin, like during the BCH fork?
Yes, it's Bitcoin Gold(BTG), may be in the future market will have a lot of bitcoin fork versions if this situation continuously going on. It could be another great time to buy if there's another big dip before the fork.
Could be, but I'm not sure that the market is quite ready for a dip like that yet. The bulls have retraced to the very last resistance before retesting all-time highs. I suspect that Bitcoin will continue to rally as there is still ample time before the real fork threat in November.
In the meantime, if anything, the Bitcoin Gold fork could be causing people to withdraw their BTC from exchanges, so they can recover the BTG after the fork. That could help drive the price back to $5000 and beyond. I suspect that November will be bearish for Bitcoin, though, as the Segwit2x fork approaches.
