If you want to see bitcoin in paper form then the purpose of creating bitcoin will get shattered.
Haha are you mean to say about the paper wallet. I don't know what will be done in the future but so far paper wallet is the only thing we can consider as a paper wallet mate.
If you want to see bit coin like Fiat cash then you have very less chance to see it.
Because it is decentralized cryotocurrency may be we can use it for long time.
Obviously he is not bringing up the idea of a paper wallet but rather bringing up having bitcoin as a paper currency which is absurd because that was the reason a lot of us are investing in this space in the first place as paper currency has brought even more harm than good with the way the government and banks have manipulated and monopolized the fiat space.
Moreover, if we should start talking about paper currency for bitcoin, which country will be printing? Decentralized digital currency is what it is and there is no point trying to go archaic like the OP.
