I do not see Bitcoin Gold's upside potential. It seems to me that this is a common publicized coin the creators of which want to promote BTG through the popularity of Bitcoin and make money from it. It is very strange for me to buy Bitcoin, which is not exactly Bitcoin and does not cost anything.
In my point of view Bitcoin Gold haven't potential. It is groving only thanks to the name, not improvement of technology, it is only using the bitcoin popularity and the FOMO in this alt season period. no one cryptocurrency can replace Bitcoin and this is for sure!
