SCAM!! Be careful. There was once a chat, supposedly giving free 0.01 trons. They made you 'invest' in order to mine faster. One day all my invested Taraxa was gone, the mods from the app disappeared, and then the chat disappeared. The smart guys took all the money and all accounts turned to zero. I hope they get cancer soon, so that they spend all the money they stole to doctors. Stay away.
