What an amazing idea to eliminate spam calls and create an environment where consumers are paid for their data rather than being targeted by spam calls. This is going to be a big industry. The opportunity to invest early in a disrupting company that solves a major pain for consumers is something I wouldn't miss.
I've been using this app for a few months now and it's worked great. It blocks calls (yet I can still get them to go directly to voice mail without disturbing me) that aren't on my contact list, PLUS I get paid in the nano cryptocurrency for each call that gets blocked. How cool is that? win/ win
