Probably, but unfortunately the answer is YES!
I have the same assumption as you
I'm looking for meaning in this, and I can't find it. I look at the source code of both coins, and I see that it is different. Why do double work? How does a WAVI get involved?
It's just an assumption... so it can be wrong. Both wavi and exvo devs disappeared in almost the same moment. Was that coincidental? More over, both of them didn't reply any issues on their official threads. Yet in fact, they had logged in to bitcointalk a few days ago. CMIIW
