It is quite important to maintain a sense of realism and judge things as they are, rather than as they appear. In the case of cryptocurrency, if one looks at the money supply of an established but by no means big country like the UK, which stands at around 1.7 trillion as of July this year, one can see that cryptocurrency, with a combined market capitalization of 134 billion, is nowhere near the money supply of a single country, let alone that of an important player in the world economy, as no doubt it will occupy such a position in the future.
