Altcoin.ac domain name is for sale
Descriptive, the extension AC also points out to altcoin

Altcoin.com was listed and most likely sold for 12 btc (nearly $1.2M at the time of sale)
You can have Altcoin.ac for a fraction of that price

I wanted to create an altcoin related project on that domain but don't have time
The domain is registered with Dynadot, we can use their transfer assistant, you just need an account there

Offers are welcome, PM me
