I joined at your bounty campaign though I am not familiar with the Campaign Manager but I think he has a good reputation in this forum. He has 8 positive trusts which I think the basis of a good and reliable person. Hope that you will manage well this project because arizn is a promising project. Therefore, its up to the marketing side to give their effort on spreading their platform.
I Viewed his/her profile seems legit to me.. I hope he/she can attract more projects in the future. The project he/she handling looks very promising to me. Kudos to the team of Arizn you made a good choice of choosing this bounty manager.
It is indeed very promising and since the private sale is sold out, it might mean that a lot also are interested and believe in the legality of this project. Soletus just wait and see.
