Letting developers know about Bitcoin is a good thing because almost everybody engulfed in using the Internet knows Bitcoin and might be knowledgeable in using it. Cryptocurrency being used in some games will be really helpful to the community that is playing that game because they can pay instantly and hassle free. Bitcoin is electronic money and wont be called fake because it can be converted into cash.
Bitcoin cannot be faked because it is a digital currency that only exists on the internet, its ownership is not in the name of people but only consists of very complex code. Whereas for counterfeiting there must be physical goods, such as cash.
So, it is theoretically safer than holding cash. Especially if a long trip takes a long time, crossing between countries, it is more practical to have bitcoin because there is no customs inspection at the airport or seaport.
