There are fossil-fuel steel initiatives like Hybrit. If coal would be more expensive we would see more of these. Bitcoin's value is through the roof due to the religious fervor of holders, greedy investors shooting for the moon, and market manipulation. This is however not sustainable since the only value is cashing out at the right time, taking money from bag holders. Bitcoin is more of an asset class than a currency, it does not offer much to the unbanked. You can't buy anything with it, you can just buy it and sell it, which is risky. People however are being scammed with Bitcoin, just look at what happened in Brazil after their regulators gave a thumbs up on cryptocurrencies: FOMO, Ponzi schemes, hundreds of thousands of victims. Bitcoin in many parts of the world finances organized crime and terrorism, so banking the unbanked is not always a good idea either.
