Not here to shit on Vcash or john-connor. I have no strong opinion on the coin and the man is clearly a very talented programmer. I just had to point out the absurdity of the statement "The ZeroLedger technology is alone worth a billion IMHO".
BTC and Vcash are competing digital currencies, not competing consumer goods. Currency and consumer goods do not derive their values from the same sources. A crypto-currency derives its value mainly from adoption, but john-connor speaks of ZeroLedger as if he is the Samsumg CEO speculating on the worth of their latest advancements in bendable touchscreens.
BTC is light-years ahead of everything else when it comes to current adoption, and this fact is further compounded by the effect of adoption begetting adoption. I can hear fanboys screaming, "technological advancements will drive adoption!". If you believe this, you live in a fantasy land that exists only in your dreams. In the real world, the majority of the population has absolutely zero interest in buying, owning, using, accepting, or investing in crypto-currency and never will. They want to swipe their Visa card and go about their day. They aren't sitting on the sidelines because BTC isn't fast enough or truly anonymous. john-connor goes on to state that zero confirmation will make crypto-currencies useful "in real time situations", which is utterly irrelevant because I have yet to see a compelling use case or demand of any significance for crypto-currency "in real time situations".
Visa, Mastercard, Paypal, and the legacy banking system are not frightened of BTC and blockchain technology. They will be watching the world of crypto-currencies and continually stealing the good parts from it to improve efficiency, lower costs, and improve their service. In the same way, BTC is not scared of altcoins. BTC will continually take advances pioneered by altcoins for itself, as this very thread vividly illustrates.
There are other use cases for blockchain technology besides as currency, and it remains to be seen whether currency is the so-called "killer app" of blockchain technology, but trying to compete with BTC when it comes to use as a currency is a fool's errand. BTC has already won, deal with it.
