Bitcoin SV may have grown in price within the short term, but it could easily fail in the long term if it doesn't provide the world with real uses.
fork coins can never become successful in the long run because they can not offer any real usages. it is simply due to the fact that they are mere copies of the original project which is doing everything they do in a much safer manner.
also keep in mind that they are going to be competing with a lot of altcoins that offer better usability than them.
