so with this clip the people are talking about creating another ledger that could rival bitcoin and replace fiat as a government controlled currency. The way that bitcoin, and altcoins, are supposed to be is that no one entity can control the ledger be they miners, organizations, or governments. There could be some coin that comes out that is controlled by an entity but it probably won't be supported by the community as a whole and go nowhere as a result. Though that remains to be seen. Continue to do research and look into things more. There are sites out there that could help, www.cryptofunds.online and helptap.com could be some sources of information as well as surfing though the boards here.
Any official government cryptocurrency is going to be same as their fiat-currency: plentiful, worth even less overtime, can be manipulated, and untrustworthy.
Bitcoin on the other-hand is (free from the central-bank debt-based system and the) ultimate store of value and its popularity has strengthened over time and maximizes value compared to any other altcoin...why?:
If it can be shutdown, and have assets frozen by a bank or government, there would be no value
If it wasn't secure, there would be no value.
If it wasn't immutable, there would be no value.
If it wasn't globally distributed, there would be no value.
If it wasn't so strong, open-source decentralized and unstoppable, there would be no value.
If it wasn't so scarce, there would be no value.
If it was easy to spam transactions, there would be no value
If it was stopped after all major banks on Earth banned in 2013 to today, there would be no value. (say "bitcoin" when transacting and watch the block of the transaction. simple fix=never mention "bitcoin").
If it didn't have the history of 8+ years (and still no hacker can exploit bitcoin blockchain), there would be no value
If it was exactly like fiat and only did transactions, there would be no value.
Bitcoin's value is worth over $110 billion USD today. Altcoins however are scams, weak, pyramid schemes not offering these values.
Bitcoin has all the characteristics needed combined to make the most value and increasing more than any other financial-asset option coming from the manipulated fiat central-banking debt-system.
