Our biggest issue is transparency. Mintcointeam claims that he's got "Big stuff comming" and everyone is patiently waiting for something to happen. A lot of grand announcements, but nothing to show for it so far. If the dev would share some of the progress beeing made, it would comfort the community and encourage people to keep mining/buying instead of trading their MINT for other coins. I sold about one third of my investment a few weeks ago because there are lots of other, more interesting coins out there with actual development in progress.
I'm not saying nothing is beeing made behind the scenes with Mint, but unless we see some progress, the majority of this community will be gone by a few months. Mint is still a great coins with lots of potential. Let's not throw that away...
