STEM is a sports team exchange where each sports club has its own token and that token has its own cost. On the STEM exchange, each sports club has a personal token, which has its own value. The price of these tokens is determined by such indicators as the statistics of the team's game, the world ranking, the position in the standings, the cost of the club's players, and others. Depending on the change in these indicators, the price of tokens changes. Users can earn from the growth or decline in the price of these assets by tracking changes in team performance.
