What Development??? They have accomplished nothing in 20 months since ICO.
Sounds to me like a question from novice who fell for the oldest trick in the scroll. In those 20 moths you ask about they did more that the whole BitcoinCore team for their baby. Ask MinexCoin team to send you Y&Q reports and if they consider that you are a bit qualified in the areas of financial soft development and good enough to comprehend blockchain based financial system they may answer your request. But I think that they will deal with a boy in short pants involved in situations like this.
