Here's just some sample domains that are bitcoin related. This domain is not for everyone so please don't offer if you can not afford it.
Bitmining.com was sold for 3 bitcoins so I'm sure this is going to be sold for much more.

I bet the owner of BitcoinWallet.com is still kicking himself for that purchase ($250k). He's not even a top 10 wallet provider.
But not the Bitcoin.com owner for sure
You are aware that:
1: Bitcoin.com is the best possible Bitcoin related domain
2: Bitcoin.com was leased out for $10k a month... only for the firm renting it out to immediately try and cut the deal (http://www.coindesk.com/roger-ver-sues-bitcoin-exchange-okcoin-570k/
3: What are other examples of generic Bitcoin related domains having any signs of success?
Its a rip off.
