I understand that Millennium Club cold staking has a nice return on investment (ROI). And one of the developers of Millennium Club, FieryDev, has been involved in the Special Coins community for awhile now.
You're right. FieryDev has been helping out with community members having questions and giving nice input. The fact that the developers of the MilleniumClub offered free COLDSTAKING BCZ from the get go without any troubles speaks for them.
