I've heard of Virie as well.. and i think that they are actually doing quite good at the moment.
As of, on or max 5 cryptocurrencies.. i think that's easier for people to understand this mecca of online coins. I think that more and more people get lost in their online research and get unsure on which to invest and what to do with their investment, how trading works and how everything helps them. Also.. most of people don't really know what block chain means or is.. and also everybody thinks that all the online investments are some sort of scams by the end of the day.
So, in order to be able to have one unique currency, i think we should first educate the consumers and then unite as many currencies in order to have less on the market. Also, by putting together more currencies i can only guess that they will become more valuable and also governments will gain their trust and so we will have worldwide crypto payments made legal.
On the other hand, what the Virternity project aims is a really cool thing. I've been researching about it, read their book/project and i really hope there is a future for the idea.
An owners free world is what i've always dreamed of! Don't you?
