PokemonGO is wildly popular. I'd be surprised if anyone here hasn't heard of it, and I'm sure many of us play it. Niantic (the company that made the game) seems to be planning on adding trading to the game in the near future. Once players start trading Pokemon, they will need a currency to value Pokemon with. We need a PokemonGOCoin. POGOC is a shitcoin I would buy in to.
We don't need it. We are told that we need it until we think that we want it.
