Why are NFT snakes constantly increasing in value?

The main driver of the growth in the value of NFT is the growing popularity of the game. The more players want to buy a snake, the higher their value. Snakes created in the first six months of the game can be profitably sold on the secondary market after halving, since halving, because halving does not affect snakes created before halving — this makes that snakes more valuable than new snakes. The cost of collectible NFT Artifacts will also increase due to the growing demand and scarcity (the number of artifacts is limited and will become more difficult to obtain over time).
