It was a great move to give FIMK holders a buyout. Just like Lisk gave Crypti holders a buyout.
Imagine if years from now the heat devs switch to a new project with a new ico. And they are building the new project on the heat tech, which you paid for with your heat investment and also the opportunity cost of holding heat for years and trusting the devs to deliver.
You would surely be demanding that heat investors receive a buyout from the new project ico in that situation.
