Coin Market Cap is the primary source for all things crypto. It gives you an aggregate price of what each coin is worth through the API's connected to each crypto platform. Each day you check in you can use the diamonds towards rare NFT drops, coin give-aways, Vouchers, lotteries, etc. There's a lot you can do with the diamonds and possibly get something rare or a jumpstart on a new coin if you continue collecting them. You can collect them by checking in each day, or guessing the price of specific crypto coins for the next 3=6 months, and if you get close to the right price, you win even more diamonds, so there's an incentive to try and guess or use analysis to apply your guesses as best as you can.
