Unlimited supply is their main argument but ETH and Doge have infinite supply as well.
This is probably an unpopular opinion but SLP should remain an in-game token that's not traded publicly. It boosted the game during its early launch but I believe devs had not thought it out properly.
SLP is just like doge coin with no exact max supply, I'm certain that if SLP has a max supply the value won't be so worthless today,
There's a discussion about introducing a SLP burning mechanism. I think it's called "sink".
the fate of SLP sticks with whatever happens to Axie infinity in future I believe this SLP will be greatly affected if axie infinity goes down
It's the same scenario with AXS. Sucess or failure depends on the project that launched them.
