The coin is expected to be listed soon, which will open the possibility to exchange collected coins on the market. There are also small daily tasks that take just 1-2 minutes and allow you to increase your coin balance if you choose to complete them. The project looks promising, and this is supported by the success of their previous game DOGS, where many participants received a substantial bonus simply for participating.
