An altcoin being on the "top" doesn't automatically mean it's a "safe" or good investment. I mean, take a look at it! The cryptocurrency market is full of crap. And not to mention that bitcoin is risky and volatile enough for the typical inexperienced investor, and you're going to say that it's better for them to buy coins like Ripplecoin a.k.a. fidget spinner coin? Worst investing advice I've read yet.
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.
