Bitcoin SV is a fork of bitcoin cash and this is one of the cause on why the market has plunged. Dr. Craigh Wright is the main dev of this coin and surprisingly it has reached #9 on coinmarketcap but this doesn't mean that this coin has that potential, it's just another fork of a fork.
I would like to agree with you, but, like you, I am surprised by the fact that BSV is on the 9th place on CMC and I'm also surprised by the 24h trading volume, which is over 80 million USD. Does this mean that there are a lot of people who trust this coin, or it's just several whales pumping it? Also it is not clear to me what can happen to Bitcoin Cash ((BCHABC) if BSV survives in the end. I personally thought that the war would be over in a week, but apparently I was wrong.
I will only speculate that the whales have been pumping it. If you would remember when Bitcoin split and Bitcoin Cash was reborn, it was really pumped hard from November - December and even saying that they're going to be the number 1 coins, but their efforts was not enough. So I'm seeing the same with SV right now, being pumped so hard but eventually if will plummet once the whales took their profits.
I wouldn't be so sure about the "profits". As far as I understand, they have been losing big amounts each day while trying to win the war. I think they can end up with hundreds of millions USD in losses. Actually what they are doing reminds me of an addicted gambler who can't stop martingaling until nothing is left on the balance.
