I do not exactly know what is going to happen but I am expecting bitcoin to rise up more in the price after bitcoin gold is launched. Some people think that it can be a scam and maybe it will also be like bitcoin cash. What I am focusing is that will people sell out bitcoin for it or not. If there will be selling out, bitcoin will reduce in the price and again take few weeks to gain value.
My thinking is that
if there is buying demand (bids) which enable BTC holders to claim this free money, that means BTG is diverting investment away from Bitcoin. Just like any altcoin, really.
I highly doubt this will be like Bitcoin Cash. That launch, rushed as it was, had a lot of hype, working full node/lite node wallets, Bitmain (hashpower), Bitpay and folks like Roger Ver and Craig Wright. It also naturally inherited most of the Bitcoin Unlimited supporters.
Bitcoin Gold has none of that. No wallet available yet, no replay protection ready yet. And worst of all, the developers have announced they will be pre-mining the chain after the fork occurs and before the blockchain is public.
It's simple. Many people will dump their Bgold as soon as they got it for BTC or for other altcoins.
As this is another hardfork of Bitcoin keep in mind that all the BTC whales will have this coin as well.
So imo, whatever you may think about this coin, scam or not, I can assure the big guys will play with it.Which means this thing will see some pump and dump plays! So if you're smart, try no to sell the bottom!
