Stop being lazy and dont spread fud about bittube based on one cutout message omg  . If you really care about this fpga scam and not just fud go to bittube discord and read everything from beginning dont fud bittube project for attempting to develop better anti-fpga pow.

Just to quickly fill you in bittube used very cpu friendly algo to make mining more effective for cpu because users used small fraction of their computing power while watching videos on bit.tube. But after some time they suspected that there may be a botnet or fpga farm which is exploiting this and has large share of their network.
So I guess to verify this fpga issue they tried to get any fpga working to see themselves if they are problem. After this testing they saw fpga are real and could work. Then they started developing new pow algo which will be much more resistant to fpga and botnets and will prefer gpu miners instead. And thats where it end I guess new pow is on live network for some time.
