Objectively, the money is just a sheet of paper, why? The paper is recognized by the state government to ensure that, so what is the guarantee? that is gold. Which country more and more gold, wealth assets are terrible, that currency is priced compared to other currencies. To understand more about currency you can see the book "War Money" nhé!
Bitcoin is generally accepted by the community and is priced against USD or gold so it's worth it.
In short, every value is converted into gold. But gold has some major disadvantages so new alternatives are available such as money and now Bitcoin.
Yes, you are right and I absolutely agree with what you are trying to point out. Clearly, the people that says that bitcoins is not deserving for the value it has and the trust that people gives into it do not understand or cannot see whole picture. Yes, they maybe degree holders and may be the best that there is in their fields and well educated but, they are dumb about bitcoins let alone this whole crypto industry. The worse thing is that they refuse to educate themselves about cryptos because they don't want to be proven wrong or even if they already did, they never wanna admit their mistakes because of their prides. Oh well, that would be their loss, not ours so I don't give a rat's ass about what they think or say.
