It is not the first time people try to bridge the gap between Bitcoin and in-game items, as there is a lot to gain for all parties involved. Most i-game items cannot be traded or sold, yet players invest a ton of time in their gaming activity. Monetizing this content is not an easy job, and next to Free My Vunk, Bitszer is one of the few other projects trying to address this issue.
While Bitszer is still in its very early days of being publicly embraced, developers can download the code and integrate it into their games if they wanted to. However, the user-friendliness still needs some work, and the team is working hard on improving that side of the medallion.
