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 with truly liberal and free alien civilizations, the blockchain technology would have attained (for all purposes) universal adoption in a shorter time that the cryptos have been around by now here.
What are your takes about that sentiment?
Not really, we do not need bitcoin to replace fiat, right now the adoption of bitcoin is low because its use as a currency is not really appreciated by the people, after all if they have fiat they do not see the need to use bitcoin, so what is keeping bitcoin strong at the moment is mostly its value as an investment, however as soon as the major fiat currencies around the world encounter some issues and people begin to lose money that is when major adoption could happen, and we are already seeing examples of this, because in the countries in which the fiat currency of the local government has experimented major inflation, the use of other currencies has gone up, including bitcoin.
