I have recently gotten blocked for withdrawing my earnings from my devices. I followed the rules. Ive paid for the boost and pro. Have yet to hear back from CT. I've promoted this app to everyone I know and the thanks I get is getting blocked for withdrawing what I EARNED? I will give 5 stars when this is fixed. *edit* emailed devs. Of course no response months later. Id recommend getting a mining rig. Don't waste ur time and money on this scam.
