Since the fork we have a new coin very similar to bitcoin , do you think it is a threat to bitcoin?
Now I have those bitcoin cash and i don't know what to do with them.
I don't have the technic gear to choose between both, and I feel bitcoin cash is taking bitcoin down am I right? It's taking a part of its market capitalization.
I don't think that Bitcoin Cash will be able to take down bitcoin. You can see it by how the people treat this alternative coin. Even it takes a lot of years, Bitcoin Cash will just be under many other altcoins and not even under Bitcoin.
