Decentralized currency has an advantage to society(special mention, Bitcoin). But never to the capitalists and traditional centralized financial institutions.
Climate change is a different story, it involves a serious situation that is connected to our habitat. Yes, a habitat that we still need to use fiat, we can't fully replace fiat, not all people worldwide have the same status. Other's lack of internet which is Bitcoin and other cryptos really need. When it comes to finances, these are instruments to control the people. So, they aren't comparable. But if the mass would demand a decentralized financial system, then I guess it will then work.
But I heard that the Prime Minister of Australia is now investing in cryptocurrency projects to save their economy from inflation and provide more jobs.
We will see it then!
Some suggested creating a system that allows sending Bitcoin through the use of a third party SMS wallet provider or broadcasting Blockchain data over DVB-T <...>
