Bitcoin Gold are not pumped by Roger Ver and his minions. ^joke^
A lot of these coins seem to think if you create a fork and you pump it a little until you can get some value for your free coins, then you can simply stop supporting it. For any coin to really work, you have to build a strong community and network around it.
You also have to aggressively market the coins to merchants to get it into shops. If there is no use case, then people will stop buying it. This is the reason why Bitcoin Gold is falling on the way side now.
Read my last second comment. Maybe you have answer of my question
Is it possible someone hire 50-100 people (developers) and investors and do new Fork of Bitcoin? and scam people? If this is possible then
This will be one more cons of Bitcoin.
