It is BY FAR the most pathetic shitcoin on the market.
Greedy devs saw that BCH was able to sustain its value and many newcomers to crypto thought that it was only because of it being a fork (without realising it is really because a lot of the original bitcoin community was backing it and saw it as a continuation of the bitcoin they knew and loved).
So they took advantage and decided to scam those people, who hoped of a similar success story and pumps like BCH had. Of course there would be none, as BTG does not have its Roger Ver, Calvin Ayre, Rick Falkvinge, Emil, Jihan, Haipo, etc...
Their stated goal was to become A MORE SECURE BITCOIN that's more resilient to 51% attacks - and they became one of the first coins to be successfully 51% attacked. This should tell you how much of a joke they are.
