Well, Bitcoin will continue ruling the world of Crypto-Currency, BTG will be distributed for free among Bitcoin holders. There is nothing wrong with this, no one is being scammed, the important here is that you will keep your Bitcoins and will receive extra free money, Bitcoin Gold. We are already receiving free coins and people are complaining about its price? Lol, better than nothing... It's surely a good idea, it won't destabilize Bitcoin and will give us extra profit.
BTG is the same as bitcoincash. so I think Bitcoin will remain number one and Bitcoin will remain the best. Bitcoin price will be quite influential, but if you look at how the statistics that occur then the Bitcoin price will still survive. the time when fork and Bitcoincash resulted in bitcoin price had decreased, but when you are patient then see that bitcoin price has reached 6.000 $. this has proven that Bitcoin has the power to survive and for me Bitcoin is the only valuable digital currency at the moment. maybe only Etherum can match the bitcoin, and for bitcoincash and bitcoinGold I think they will not last long.
