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 ??
The decision is yours, but I don't think that Bitcoin SV has anything real to offer. Ethereum, on the other hand, does. And, with Ethereum 2.0 on the way, it will likely become much more modern, which is its only real flaw right now. Not to mention that even in this state, Ethereum still dominates as a development platform, and the fabled 'Ethereum killer' is nowhere to be found. Shortly, I would say that ETH is a better option.
