I'd suggest you stay away from this. Probably the only reason there are no reviews online is that people have not heard enough of it yet. I also looked it up on binaryscamwatchmonitor but seemed they haven't heard of it as well. If it sounds too good to be true, it probably is. My cousin convinced me to invest a few bits in btcriver so I just sent a small amount despite my suspicion. I checked said monitoring site I mentioned. There were few comments but there were people complaining that they can't get their interest out, despite the site still working for majority of people. 2 weeks later the site went offline. And everyone were posting comments. I found it surprising they never caught wind of what's happening.
