In my opinion it will not be wise to invest in BitcoinSV as most of the time it looks like pump and dump. To be on a safer side it wou ld be nice to still do your own research in the top 10 coin.just understand the project and analyse the last six months development news. It would give you a clear picture of the project.
I'll take that to the next step— I think it's not wise to invest in any other cryptocurrency in general besides bitcoin, simply because bitcoin is what mostly matters anyway. Most are just noise.
