It was my understanding that bitcoin cash (BCH) is no more, there is now BCH ABC and BCH SV that have been issues 1:1 in replacement of any BCH holdings. Perhaps I am mistaken in this?
You are correct. As you can see from coinmarketcap, most exchanges have already switched over to listing
BCHSV and
BCHABC.
With BCHSV trading at 0.016BTC, and BCHABC trading at 0.044BTC, for a combined price of 0.06BTC per forked BCH, it means this fork has lost BCH holders about 25-30% of their money, as BCH was trading at around 0.08-0.085BTC prior to the fork.
At least one of these forks, probably SV, is going to rapidly fail. ABC might stick around for a while, but all it will manage to do is continue the slow and prolonged death (with the odd pump by the scammer Ver) that BCH was undergoing long before this fork was even announced. If you still holding any of these coins, it's time to dump them before they lose even more value.
