Yes, that's the part im struggling with in my approach. I agree with you that "Bitcoin is not crypto" is a way to distinguish shitcoins from crypto.

So I would definitely hesitate to say "Bitcoin is crypto" since I will indeed be misunderstood but then I accept that crypto means cryptocurrency... 

Which is contrary to what I want to do, lol

Bitcoin is no crypto is a way to say that Bitcoin is different than other projects who are not decentralized and open.

We can say that being crypto is the less interesting part of Bitcoin.
