Thank you for your questions. Let me answer.

1. Blockchain is necessary to ensure the safe and decentralized storage of data, transparency of transactions and fair calculation of rewards without human intervention.
Also, thanks to the blockchain technology at the current stage, we have the opportunity to further scale and use it for the development of the planned functional without the need of refactoring of the entire ecosystem.

2. Why not about sport and good quality motivation? It will not harms the person, members of our team have been involved in sports for many years, it will harms your health if you trying to do it at professional level. But we promote active lifestile and socialization. We want to motivate people to go for a walk, light jogging, bicycling etc. more often and most importantly, do it not alone.
