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.
If you're good in CS:GO then you can surely make money out of it. 0.3 BTC is nothing compared to how much pro players make when there's a tournament. And also most of them sell their items. Items on CS:GO costs really much especially those that are very limited.
I encountered someone on a gambling site that has multiple websites that sells CS:GO items. He said he has a supplier for these items. He said he makes thousands of dollars from that. It seems legit to me, though, because there are thousands/millions of CS:GO addicts. Bottom line, this is just another method of selling digital goods.
