I know there is one that you get BTC on mobile from walking around and finding dropped coins, forget what it is called though,
Lol what? That's impossible. Probably only faucet with some fancy feature.
I am not sure what is that, but it sure reminds me of Pokémon go. You 'go around and search for Bitcoin(Pokémon?). Seems like just a joke or something, but it would be good if it exists. You just pick up Bitcoins and transfer money to your wallet, that would be awesome if someone made that.
A Pokemon Go cryptocurrency variant game would be a good idea. You go around town looking for coins and the most you get are the most common one like dogecoin. Sometimes you can let some litecoins of you are lucky. But what you are really after are the bitcoins.
