Could you please tell us about the browser and app you are planning to create. Are the Mass coins part of it? or is it something similar to Adblock or Brave browser?
I understand the value of Adblock and its big battle with Facebook whose only revenue is via advertisements, so too is Whatsapp, so any block to the advertisements is a huge blow to their revenue.
I only want to invest in a product, not just another ICO. I know a lot of folks here just want to make a quick buck as soon as its traded on the exchanges sadly.
Mass coins are needed to run the marketplace. Sorry about just providing a link instead of explaining, but can't make it any better.
The main ideas are: the internal currency is needed to make the economic relations within the system independent from external factors. Assets attached to a blockchain (as colored bitcoins) is the best option possible having no unneeded complexity and, therefore, instability.
