I'm passionate about Bitcoin but I'm also passionate about technology. I think it would be narrow minded to dismiss all other technologies. Am I going to invest in XRP? Hell no. But I'm open to hear about new technology being created. So far, I don't see a compelling reason to purchase any other coins because none of them do what Bitcoin does. I think blockchain technology has a lot of promise in the future but Bitcoin needs to be more mainstream for anyone to take blockchain seriously.
