Unmoderated OPAIR thread, many suspicous or proofs are listed here in this thread.
https://bitcointalk.org/index.php?topic=1570330.0OP is self-moderated https://bitcointalk.org/index.php?topic=1558596.0
Reasons:
1. Was no escrow, after investors accused it, OP used escrow, but the first round of ico about 70 btc were not sent to escrow service. So Most of the btc fund is still NO escrow!!!

2. Fake LinkedIn pages,
Frank H. Rettig (CEO / Founder)
https://www.linkedin.com/in/frankhrettigHao Wang (Core / Platform Developer) https://www.linkedin.com/in/haowangg
no more info about 2 devs: Frank and Hao in google,
This is one HAO WANG, but he is not the dev, although their CVs look same. http://www-scf.usc.edu/~haowang/index.php
I suspect wasserman(Opair OP) stole this CV and modified. I contacted the address in the webpage, but no email replied
3. Refuse interview&google hangout, wasserman(Opair OP) claimed they afraid personal attack, and no time(WTF, you want 700 btc but you don't have 1 hour time? And who will attack you if you devs are real, big lie!!!)
4. CEO said he was watching BCT forum since 2012, while he is a passive reader, he has NO BCT account. (WTF, how is possible? Obvious lie)
5. CEO's statement about OPAIR
