As for me, a bad idea ..
My personal experience :
Revizor - scam,
Giza device - scam,
Renberry-  he collected 30 lyams, he did not pay bounty...
FinTAb - 3 months can not be listed on a normal exchange (but for me it is one of the most successful projects)
At the moment I have high hopes for the Russian project - allabout.me
