I don't know why MNX has decreased too bad recent months. I was a translator for Minex project before they launch their ICO programme and I was very impressed with their whitepaper because they said that they have the @minexbank which can maintain the price of its ecosystem. So now? maybe that Bank was destroyed or shut down, lol. Anyway, I'm still hold Minexcoin because I believe they can revive their project 
. Futhermore, I've ordered the Minex Card but it never came.
You missed a lot of events from the moment when the ICO was over. Now the project does not work with the supplier of cards that you ordered. They build channels with a new cards provider. And now there is still no information about the status of the relationship of the team and the new provider.. Futhermore, I've ordered the Minex Card but it never came.
