Bitcoin cash is a result from the fork of bitcoin, it is not a good coin, it has no projects, not dev, nothing. It is a speculation coin, if you wanna hold it it can drop anytime. It is free money, why dont convert it to bitcoin or to fiat? I converted it to bitcoin when it was $700 each one, i made a good profit
I heard many merchants are going to support it. If you read reddit/btc, there are many supporters there.
The issue for merchants is that transaction fees for bitcoin are too high and the length of time it takes for transactions to be included in blocks is also too long. So they will either switch to bitcoincash once it stabalises, or look for an alt.
Look at the number of exchanges that allow you to change alts like ltc, eth and bch directly into fiat, so you can bypass bitcoin. That is a trend that will continue.
