Yes, one can speculate about that. But the reasonable assumption would be to expect more coins in the order books now than three years ago, for a simple fact that not all the coins mined in the last three years went directly to the cold storage. Simple?
but there are also more users, more genuine usage and more awareness. i think that means more coins will be tied up. I think it might balance things out but let's see.
If there is no block size increase, it will take longer to get a ATH.
