Yes it is. The platform itself uses a Free to Play model, which can be seen in a lot of games. Whilst the platform itself is no risk and needs no capital investment, there are in-platform options that could be additionally purchased.
For example, players can receive new start-up capital ( if there was a margin call) and gain other exclusive in-game bonuses. For example, there will be a "Follow me" program in Professional tournaments where, for a small price, players can choose a leader/favourite player on the platform and monitor his trading online and learn from his tactics. The leader player will be paid the majority of that money, with a small percentage for us. Thus players can earn additional earnings from their skills whilst we help bring the learner and the professional together.
