You are wrong. BTG price dropped 97% from its INITIAL VALUE. Pls go check some other coins: their initial value and current.
What does "INITIAL VALUE" mean? Zcash at it's start was about 1000 BTC per ZEC. And so what? Is it initial price? It should observe any coin at least several month to get it's more or less adequate market price
You are wrong again. ZCash initial value against BTC was 1 ZEC = 6 BTC. However ZEC has its own code and products. BTG does not have anything except copy-pasting original BTC code. There is no purpose in BTG fork. All coins that are inhereted from BTC are useless:
1. LTC is a useless shit (even Charlie Lee sold out top and said he will never buyback)
2. BTG, BCash, BTD and other BTC forks are useless shit because main development is only in BTC codebase.
The only purpose of BTG and other forks is to have big premine (200k BTG coins) and sell it on top from initial value, because price will be in constant decline. Please check BTG price chart for more info.
