Bitcoin is one of those technologies that can change the world permanently. Not just the economy, or just the Internet, but everything and everyone. That's why I think it's a pity that every week there is a pile of technical and economic scientific paper on Bitcoin, blockchain and cryptocurrencies, but sociological and cultural studies publications are still in short supply.

That's right, friend, there's so much reason here. This will change the equation of supply and demand for banking. It's that big. I am not at all surprised that bankers, financiers and Saudi princes are coming out against them.

A clear example of this new form of financing has been the announcement by the President of Venezuela, Nicolás Maduro, of the creation of a cryptocurrency, the "petro", which will be backed by the oil, gold, gas and diamond reserves of the country to fight the financial blockade submitted by the US Department of the Treasury.
