While I certainly agree that ICO ideas could use a tighter filter and founders need to just be willing to build on traditional platforms rather than crypto for the sake of crypto... this actually has a logical impetus if you think about it. You're throwing a whole bunch of people from all over the world into a basket to learn a language. How are they going to pay? USD? But they haven't made it to the US yet and why deal with all those conversion rates and non-global processors and folks who don't have Mastercard? What if you're going from baht to pesos? Sounds like a nightmare. They're promoting cross-cultural learning, why not use cross-cultural money - a crypto. Level the playing field and cross any border necessary with a token while funding the project to launch it at the same time with loyal fans and potential customers. The audience is 1) people who want to learn a language and 2) people who own BTC, ETH, or ESL. This seems like a focused yet large enough niche to gain traction with a project.
