I do not believe in bitcoin gold because I think BTC gold will not be worth much when bitcoin is still alive and well. People will not invest in a copy of bitcoin because I think it would be risky. I would choose to invest in altcoin, which is a safer way for me.
Yes I have a doubt also in btc gold future. It just creates to earn who develop's this btc gold, it aint good. Maybe for those who really wanted to ride in this btc gold. I still choose other altcoins than btc gold.
