The exchange you mentioned did that to seek more exposure to their platform I think Binance did similar thing to other African countries, especially this was done In Nigeria to seek attention of the youth over their platform and they ended up making a nice catchy awareness to their platform. This is another good way of marketing strategies, any exchange that wants to embark on this type of awareness are all doing it to gain more people sign up on their platform, some of them would even launched an ambassadorial program to fully catch the attention of the youth, however the Crypto industry is clear open and one could learn to advanced himself without any exchange or project empowering the youths usually we know the attention of the youth are automatically driven to the crypto industry and digitalization this alone already gives rise toward the max adoption of cryptocurrency at large.
