Is investing in Bitcoin SV will be more beneficial as it haven't shown full potential yet or ETH will still be dominating in the time to come and should hold onto it ??
Bitcoin SV is by far better altcoin than Ethereum. If you look at the cryptocurrency market you can see the Bitcoin SV has a better result in terms of price-performance. Some experts even believe that Bitcoin SV is better altcoin than the Bitcoin cash BCH itself. I think we will see the full potential of the Bitcoin SV during the next market bull run.
Despite all what have been said, seen and wrote about Bitcoin SV owner price manipulation and Satoshi Nakamoto impersonation habit you're still blind by the price performance of Bitcoin SV in the crypto market. Besides, those expert you mentioned are just members of the Bitcoin SV pump and dump group.
I will advice you to learn more about crypto investment very well cause a lot of false and misleading information are share by people which seems to be expert these days.
