Yes these currencies are only for the use of traders that they do trade with them and are earning money. Some may adopt them for their businesses for giving support to these coins but in the long term it may not survive and Bitcoin will be the one coin which will be accepted globally.
Although Bitcoin SV has shown a great growth, and it is in the top-10 now, I remember that Bitcoin will be always the best cryptocurrency. I will work with it and not with the forks as I trust BTC always.
