Is Bitcoin ready to change to current bank system

Come on Hive account@d3cr33 sunny decree We all like the idea of everybody going from FIAT to crypto, but let's be real. BTC or any other blockchain product is not ready yet. No good infrastructure, no scalability, no grantees.

If SWIFT sees bad transactions, they can revert that. Can blockchain?
What about forgetting private key.
There are so many regulatory issues, no wonder why guys in charge try to stop LIBRA.

Idea is cool and maybe we will take something from it in future or taking even now, but it won't work they way that BTC just change the FIAT
