Please clarify. Is Bitcoin Cash the same as regular Bitcoin?
bitcoin source code is open to anybody to see. it also has a license that lets you freely copy it without any obligations. bitcoin isn't owned by anybody either.
as a result in the past 10 years anyone who wanted has copied bitcoin and created their own altcoin. bitcoin cash is one of many of those altcoins.
It seems to me that awhile ago Bitcoin owners were being encouraged to move their Bitcoin into Bitcoin Cash in order that they might receive twice as much return from it than if we left it in Bitcoin. Is that still the case?
no it has never been the case.
the difference between BCash and other forks is that those who created this altcoin have enough money to advertise it. and that is exactly what they have been doing. they fool newcomers into buying their altcoin so that they can earn more money.
