Found this on reddit - hope its true as i have 13k of these simply by luck, and down to switcheo!
"Seems like an alternative and more efficient way of launching a smart contract or asset on NEO. Instead of spending 500 GAS, if you have 10k MCT you can stake the MCT and spend 90 GAS to launch an asset/contract.
Also, and I may be wrong, but the MCT may be reusable for multiple contracts - something along those lines. By my math, 1k MCT has a value pegged to 40 GAS at a bare minimum without the reuseability factor.
Essentially, if you sell your MCT early you will forever regret it because it was distributed equitably instead of the richest holders and you can bet that lots of people will pay a hefty price to get to 10,000 MCT.
Edit: someone correct my if I'm wrong but 10,000 MCT = coupon to launch a NEO contract nearly free of charge. And they're not easy to buy. Anyone selling now is ruining their life."
Probably explains why a new users first post was trying to buy some, lol.
