Everyone loves getting stuff for free? Right? Great! Like many other previous versions of Minecraft PE, the new 0.16.0 beta builds have an interesting duplication glitch you can exploit to quadruple your diamonds.
In the video above, YouTuber AA12 shows off how to use this duplication glitch. It’s very easy, and all you need is a hopper and a chest. Be quick though, as the developers will probably fix this glitch very soon.
