Coin Hunt World is amazing!
Simply put, this newly released game will give you small amounts of BTC and ETH by opening 'vaults' spread around your city. Playing this game is similar to WeNano (but much better), and will require you to physically get outside and go for a stroll to 'find' these vaults.
There are different types of vaults spread around your city, and they all give different rewards, but most commonly a vault will give either $0.20 USD or $1.00 in BTC or ETH. (You get $0.20 from blue vaults, $1.00 from green vaults)
However, to open these vaults, you need to find their corresponding keys (blue and green keys)! The keys are also spread around your community! When you unlock a vault with a key, you'll have to play a round of trivia (which imo is quite pointless), and if you get it wrong, the vault doesn't open. But that's fine because if you have excess keys you can try to open the same vault again!
After you open the vault and receive your crypto (and some in-game perks), the vault will respawn in 12h or 24h depending if the vault was blue or green. This game is currently only available in the US and Canada, but the devs are actively trying to expand this game to more countries.
Now you might be quite suspicious as to how this game makes money, as I was too. According to their discord, this game makes revenue in 3 ways:
1) by selling some exclusive cosmetic items for your avatar (crafting recipes).
2) by charging token teams who want to use the platform to educate users about their tokens.
3) by marketing programs with businesses including brick-and-mortar ones that can take advantage of this game's foot traffic.
Now what does this app look like?
Okay, so I've briefly explained how this app works, but here's some of my gameplay and I'll be explaining what I show.
Here is a picture of me at a park with a lake. As you can see in the distance, there is a green vault and 2 keys in the distance.

I was only able to get a screenshot of this park, but when I was at the mall, there were much more keys and vaults lying around.
Now this may seem very well, but don't count on this app to make you rich. On average, I could get a few dollars spending a few hours with my bike going around and collecting keys and vaults. But this app is perfect if you use it on occasion to encourage exercise (of course with adequate safety precautions)
If you're still reading this, you may be delighted to hear that there are more vaults (and much more in-game gameplay that I won't spoil out here). As for the vaults, here are the rest:

But don't be surprised that (as per my knowledge), there aren't any purple vaults available. I haven't seen a yellow vault either. During special occasions (like Christmas, Chinese New Years, etc), there will be a few red vaults that last for a few hours!
Now how to install this game?
Android users can find the app in the Play Store. Users on iOS need to install the TestFlight first: https://apps.apple.com/us/app/testflight/id899247664.

If you've found this article helpful, I'd greatly appreciate it if you sign up for this game with my referral code:https://coinhunt.gsc.im/nteKOJuJ5K
If you do, both of us will get a benefit. (To be specific, you and I will both get 2 green prize boxes when you get your first green key and set up your HQ). Also, it's very good that there is no link between our accounts, so you don't have to worry about seeing that I invited you or that nonsense. There's no way of telling if someone signed up from a referral code or not!
