Sorry but we don't know anything either about the other ones... Cryptocurrency and the whole blockchain technology is still an UFO and apart from seeing some teams gathering from nowhere doing some PowerPoint as a roadmap and publishing some whitepaper to give themselves some credits I really don't see anything interesting about all the crypto market... what I am trying to say is that no one gave a shit about the person who created Bitcoin, people are just searching for alternative solutions to the actual banking system although in the case of PAC there is a team which is working really hard at this time to make things clearer and better so just be a little bit patient... frankly I prefer to see PAC or any other coin that can be mined than that shitty Ripple which is backed by all the usual suspects...
