is it possible that we can use bitcoins in buying all commodities not only in one country but the entire wold? and how will this affect the economy.
No.
This would require everyone to use bitcoin. For obvious reasons, bitcoin cannot be used everywhere (or outside of a wifi field, for that matter). there are some situations where you simply cannot avoid fiat; physical tokenized value just makes a lot of sense for the way that we conduct business in this day and age.
Moving on to the network. Scaling be damned, if we attempt to process even a fraction of the transactions ACH sees in a day, your miner would ignite in protest
we would need to do alot to accommodate all that traffic. and to be honest, it would be inefficient to use the network in this manner. fiat is very quick, very clean. the only processing power you need is the calories you used to give a person back change.
while bitcoin is groovy, fiat is the boss daddy.
but if you can print out btc paper dollars, well, that changes everything.
Btc printed on paper? I remember there is someone who did it before, a physical form just like
Casascius physical bitcoins, but I can't find the any links about it.
I do not agree if we need everyone to use bitcoin in order to buy commodities all over the world.
Because, we can do it by contacting someone whether in this forum or outside, who provides something that you need, even though it's risky and you can buy it in the country. But, if more countries legalize bitcoin or isssue some regulations about bitcoin as a legal payment, then it will be easier and become a great support for bitcoin growth.
You are right, I misspoke. I meant the supply chain of consumer goods instead of everyone. Producers/ raw material processors would need to accept btc, which mean the folks that construct the factories, and the workers in the factory, would have to accept btc. next. the people that buy these raw materials to turn into consumer products would need to be able to buy them in btc, and sell them for btc. which leads to the warehouses, and finally the consumer storefronts, who would need to accept btc as well as pay wages in btc. So finally, the consumer would need to buy the product in btc, meaning btc would have to be ubiquitous enough to be a common form of value.
all that, seems like a LOT of adoption. and we just barely solved scaling. essentially, bitcoin will be long dead and another alt will have taken its place at this point. after all this time, bitcoin is still bleeding edge and unadopted. it will take a fresh age for the level of adoption needed to foster this.
I remember hearing about bitcoin printed out like bills too, not a paper wallet but an attempt at a bitcoin fiat. Now that I think about it, it pretty much would be a paper wallet, the key to the funds would be required unless there was a trusted, centralized issuer. which flies in the face of what bitcoin represents
