Bitcoins and other cryptos will never become mainstream before... people can buy water bottles with them.
Quite simple, many expecting an explosive entropy of the bitcoin adoption / price but truth is the average folk most common needs and use of money aren't met by bitcoin, this fact goes against the very foundation of any successfully implemented mean of money anytime across recorded history. It really is a political problem at it's core, the deep states run by bankers won't let a viable alternative co-exist in the streets, I have no doubt that truly liberal and free alien civilizations, the blockchain technology would have attained universal adoption in a shorter time that the cryptos have been around by now here.
What are your takes about that sentiment?
