i think it is impossible. in my opinion crypto will live until forever. People love crypto space. and they really love the chance of earning good money in short time like a gamble. Because of that i believe crypto space will continue like that. and we will also continue to increase like past years.
I don't mind if crypto lasts forever but earning money with it is not what Satoshi himself envisioned. He meant crypto, that is bitcoin, to be the money. Do you earn money with money? Yes, you do, but this is not what money is or should be used for. Money, by definition, is a means of exchange, it is not a means of making more money directly, through trading, even though there are currency markets. Bitcoin, as of now, is not money, it is a vehicle for speculation, while most other cryptocurrencies are downright scams, going from pump to dump and then biting the dust.
And that may be the reason why he is no longer interested in bitcoin. It is possible that he was disappointed in how it would be used and left the scene at the right time.
