For me, a coin/token with an unlimited total supply is a disadvantage. Not only do we have to fight volatility, we also have to fight inflation, and those are two very negative points in cryptocurrencies. I can understand that there are very high supplies, with billions of tokens, they can always be burned, also those with an unlimited supply can be burned, but from the beginning, I don't like the feeling they give. Also, now Ethereum has to fight its high transaction fees, if we put it all together it seems crazy to me.
Yes, I agree with you, It will affect to inflation and cannot be controlled.
Limited total supply is better for price.
They can burn the supply to improve their price.
As long as many coins have burned, and the price will go up.
