Questions about ENS domains

dfmines Cryptocurrency News January 25, 2022 | 0

Hello, I have some questions related to ENS.

Someone owns the ENS address that I want to purchase. On opensea, i can see that the address is not for sale, so I was wondering how can I make a proper offer? There isn’t much price history other than 2 offers that expired (one for 0.09eth and 0.05)
Are there still ENS domains that are unclaimed? If yes, how do you purchase them?
