To understand how serious that mistake is, I invite you to read these 2 threads:
Im affraid if people making such mistake they are not really focused. I mean not mistake from just beign not focused but too spread in terms of crypto coins. Focus on BTC. Focus on BCH (?) but not both.
Many people lost BTC because they tried to cash out BCH and failed miserable due to trojan horses, mistakes made like this topic describes or many more.
