...compared to say u.s. dollar bills which you can hold in your hand or stuff in your mattress.
this is why bitcoins will not go mainstream because majority of human beings on this planet do not have access to a computer.
successful gold standards are things like toyota trucks, ak-47's, u.s. c-notes which thrive in places like afghanistan and africa.
I think comparing Bitcoin to physical money such as u.s dollar is irrational as both exist in their own circulation both have unique advantages and dis advantages as for real money/fiat can be physically felt why bitcoin is a virtual currency though it has no physical image it circulates in virtual world and serve as mediator or third party for online transaction to make our payment system more easy and less complicated. even only 10% of the world population will use crypto currency specifically bitcoin it would still exist and never vanish.
If you really want something to do and succeed then you have to do things out of your comfort zone. In this case making the lack of computer as an excuse to say that we can't access btc is a poor idea for me. It's not just computer that we can use to do it remember that btc is accessible through our cellphone as long as it has the capato enter internet.
