Honestly, I don't know. I'm thinking mostly of "active" coins, not those that haven't moved in years. I personally think that Satoshi's coins will never move.

So even if it's a minority at 20%, that's a pretty substantial number, and I can't imagine why it won't grow. Bitcoin's success depends on mass adoption, and I can't imagine a scenario where Jane Public would rather learn the technical skills to secure a local wallet versus trusting a company like Coinbase or Circle.
