With that definition, a coin is "not Bitcoin" if:

(a) it's based on a blockchain that doesn't begin from the Satoshi genesis block,

(b) the blockchain does begin from the Satoshi genesis block but is not the longest chain composed of valid transactions.
I do agree with your definition of an altcoin Peter R, well done. Smiley
