Gaming industry is a very big industry. It has a lot of users and a very big liquidity.
It will be very good if gaming industry will interact with cryptocurrency and blockchain.
In such case gamers will have more abilities to earn money.
Many people play games and spend a lot of money and time for gaming. People are ready spend money.
But thanks the appear of NFT the situation has changed. Now it is possible not only spend money but also earn money by playing.
You don't call that "spend", instead, you call that "invest".. because you buy an asset in order for you to earn, just like the popular game axie infinity, you will have to put an investment to buy axie and then you can earn SLP, that's what you are going to sell to earn money.
