Thank you Steven, I think that the word Servo could work with many many meaning like when you say a Bitcoin Servo it gives the feel of the place where Bitcoins are made or a place where you can mining a Bitcoins.
It's worth what ever you paid for it, first and second it's worth whatever someone else will pay for it.
I have domains that I personally like that no one else does. I have had domains that after I purchased I thought no one would buy and they sold.
Its not a bad name, but from prior experience i've bought domains with same keyword "servo" and they didn't sell. I even had syrvo.com that I let drop years ago.
good luck
