BITCOIN “FORKS” do you own due diligence. I have a list of approx 40. I have researched all of them and find around 20% seem to have a serious attempt of a web page, secure site github support real team of developers. The rest seem to be a copy and past of Gold and Cash to various degrees. Wiki has sanitised their site for some reason, which provided a good first source. Be vary cautious as most will try to scam your private keys and extract any BTC, BTG BCH BTX etc... later on.
