Hi,
Don't know exactly if it is the right place i was just wondering, how much ethereum.* domain is sold for ?
It all depends on the domain extension, so it would help if you can point out which extension you want to know the value of. But then again, even if people here say it's worth $100 (could be any amount) the price in reality is likely to be far lower because in +95% of the cases nothing is being done with them.
The higher valuations mostly come from businesses wanting to develop themselves around a specific domain, and in case these businesses aren't in the market for your domain, you'll be left with something that has (mostly lower) speculative value only.
