If you play League of Legends or Counter Strike you can earn digibytes, they have a really low value but it is enough to get you started with small trading.
I never heard that we can earn money from playing these games also. I am a player of Counter Strike on Steam. Can we earn these digibytes from steam or somewhere else?
but I don't think we can earn 0.3btc a week with just playing games. if it would be possible then no one will do hard work and survive everywhere.
