Quick ahead 11 months, and the rate of Axie NFTs and the game’s Clean Adore Potion cryptocurrency have collapsed. There are many motives why, but one of the most crucial is a hack that took spot in March.

A hacker managed to exploit the Ronin blockchain that Axie Infinity utilizes to steal $620 million worth of crypto.
