You know I have even messaged them and they reply really fast. I have checked Etherscan and they send their tokens. I have bought a small bag just to try. I think it differentiates from LEDU or other educational tokens. All previous projects used to focus on a very narrow branch and STC aims to cover all the gap in the educational market. I mean they gather money now to realise next phases of the project development and to be able to finance the mail ICO. As far as I know students from those leaving universities are their ambassadors so make some reaches but play various roles depending on what they specialise in. I think it looks attractive because those people know other influential people.
I see clearly how educational world suffers now because of covid and every initiative is so supported. I think they used their weakness and change it into their power. They are creating their educational section for free and and they want to pay people who finish this successfully. They make airdrops for every student who claims that.
