If you look at what historically was considered currency, and still is, bitcoin has all the attributes, and it is the most advanced cryptographic platform ever. I think that opinion on BTC can be the best expressed using the immortal words of Chinese premier Zhou Enlai, who when asked in 1970 what in his view was the impact or French revolution, said: " is too early to tell". US Treasuries, currently the base of all currencies in the world, is considered the only "risk free" debt. And I am not sarcastic, that how it is called in banking. To insure 10 million $ in US Treasuries cost you just $10,000 on CDS market. Everybody's else sovereign debt is higher risk. That means if $ CDS goes to $40,000 (Canada or Poland), everybody else is already presumed dead. And I do not know why Russians, China, India would be so attached to using $US as a final settlement currency, US dollar, if, according to the Modern Monetary Theory, this currency can be created at will by US Congress. That would dispense even with the current smoke screen of US Treasuries being "debt", the debt that no one is planning to repay ever, except for printing new money. In the meantime, bitcoin and blockchain are one of the most interesting stories of recent times in computer science, comparable only to AI. My last two projects in IT was deployment of blockchain based accounting systems for large banks. Elon Musk will be the recipient of huge Green Deal subsidies from that ^ trillions and he has to show something for it. BTC is not essential to him in any way.
