There is a lot of ignorance going around here.
Bitcoin SV is cheaper because it can handle vastly more transactions per block, making it more efficient.
Bitcoin SV believes in unrestricted scalability. Yes mostly this means miners will tend to agglomerate, and specialize I to big data center. Well know public entities that must follow law. but we believe all miners also have an incentive to not let any other gros past 50%. Today none is more than 38%, so we're safe.
And also we have had big blocks with hundred of thousand of transaction. these block generate a lot of transaction fee, sometimes more than the mining reward ! Which we all know will decrease over time, to only rely on tx fee. Which BSV embraces. The node has been worked on to support Tera Node, with Tera Block, and billions of tx, the world of tomorrow, the enterprise grade blockchain. Yes indeed it's more environmental friendly to be more efficient.
