The ideas regarding cryptcurrency in different types of computer and mobile gaming application is not a new issue since the first launching of games are using virtual money to buy items and to upgrades as a premium account. However this new generation of mobile games (Ludena Protocol) is more interesting because by playing games you can earn coins or token. This is not a bad idea at alll for all crypto enthusiast because they can sell their token on the designated exchange but collecting users information in not a good thing for me because this can be done or use in different fraudulent activities.
