Buy a CryptoBox
The CryptoBoxes have a fixed price, but they can only be bought using CBOX coins.
The contract will choose a random multiplier for your CryptoBox. The multiplier has a range from x0.3 to x400, depending on the CryptoBox.
After the contract chooses the random multiplier, it will choose a random coin to convert your reward. (BTC,ETH,LTC,DOGE,SHIBA,CBOX)
