Well done Casper team, such a good effort to promote the Casper API ( don't expect this one to educate those who support the Casper team in this thread ) .I'm glad that the team is busy to do such a good strategy to advertise the uses and importance of this project. Credit to the writers and cartoon artists! It simple but I enjoy it a lot, so unique and effective! Just continue to do unexpected works that easy to understand like this.
