I think it's a bad move for Crowdholding, I have only heard scam rumours about DeepOnion and so they shouldn't connect themselves with them.
Def not a scam. They give tons of people free coin weekly and the community is rock solid. Come check it out so we can change your mind.
As for the thread, any kind of growth or partnership is a good thing. DO has had a solid future ahead of it already and keeps adding to it. Totally happy to see this.
