This is what I deduced from a communication from Lisa.
Virtua is going to search "your exchanges" not every one, to give you the best fees and prices. Virtua will put all your cryptos and your exchanges on one page. That is if you use one of the exchanges listed. As time goes by, they will probably add more exchanges and cryptos. With NSAV/SBC starting an exchange, I see it as becoming important/promoted on Virtua. The BETA will allow people to see what they have to offer now and when the site opens to the world "provisionally" on May 31.
