It would be good if the bitcoin can be used as a currency in some games. And people can earn that in games.
let's wait for more scaling first. if some of the big online games started using bitcoin the whole network would seize up even if they were using payments channels. at some point the coins have to come out of the game and on to the blockchain.
certain games probably have 5-10 times more than the total of current bitcoin users.
That is for sure a great market to hit with bitcoin, making bitcoin more popular, games industry has a lot of people around them, like porn industry, both industries are great to bitcoin reach mainstream over the years.
I believe this new hasnt yet any affect into bitcoin value, as the gamers accept and use bitcoin it may change but now bitcoin is just a baby at the gamers hand, the first step has been made.
even bitcoin is part of the payment method in steam but many players would still use the traditional way of purchasing items since they dont even know what bitcoin is and how to gain it. but maybe some would got interested and thats a good public advertisement for bitcoin.
