The bitcoin final or btcf is not bitcoin itself. I dont think it is forked from bitcoin but it is a lookalike, a bitcoin wannabe. It has also 21 million coins in total supply and is already traded at SouthXchange. This coin was launched last 2018 , Im not sure about the month but I believe it was march. Their website was not online, the volume was not that good in trading. I am not saying this is a scam but the coin needs more promotional materials and increase in marketing. Even if they use the name of bitcoin at the beginning of their name but still you need to work it out more to make this project click.
