It looks like the project is not live, the volume per day is less than 1 etherium. Although the idea is very good, but poor marketing.
they don't believe it, when we all say that is a marketing problem. they keep saying " the product, the product" .. but the product is useless without marketing. with marketing you can sell and hype also scams, and without marketing the best project can easy fail.
And seems that qvolta failed and right now is 100% dead.
the current Qvolta project can be said to be dead, but if the team has the will to revive their marketing, do you think that Qvolta can return to life?
