Blockchain gaming has just started and is currently booming. At this productive pace, many gaming/NFT projects choose to mint their own tokens to raise capital for development. Even though it is preferable to have decentralized and disconnected gaming ecosystems, using many different tokens for different games becomes a burden to players. With the In-Game Exchange Wallet, players are no longer forced to buy different tokens from different exchanges ; instead, they can convert SPIN Tokens in the In-Game Exchange Wallet.
