I have been studying this quite a bit and one thing strikes me. The overwhelming balance of informed opinion is that BTC is a bubble, many going as far as to agree with the
Boss that it is completely without value. I'm afraid I concur with that view. Let me explain.
First of all let us dismiss the smarty pants claim that conventional currencies have no value. These days they do, like BTC, inhabit a digital world, they are mere numbers in our bank accounts. But these numbers mean something, they are evidence that we have a debt from society. In fact under the Fractional Reserve system this is very plain. As a gross simplification imagine the pensioner with €300K in her bank acccount. That €300K is lent to a young accountant as a mortgage. The accountant undertakes to provide accounting services to the value of €300K to settle his debt. Of course this is far more accounting services than the pensioner could ever want but you know how it works. One of the unknowns in this is the price level at which the accountant will provide his services. That is a key function of society, to manage the pricing process.
Now with BTC
ALL you have is a number in an account. Other than the entitlement to transfer this number to another account there is no other claim on society or anybody else, implicit or otherwise. Is it a fraud? I certainly would not accuse its enthusiasts including those in this forum of being frauds in the colloquial sense. But its terminology is borderline fraudulent. Calling itself a currency in the first place is a bit shaky but where things get distinctly suspect is in the "mining" metaphor.
fpalb has given us an excellent and stark description of the process. Here's how the metaphor goes. The miners expend enormous amounts of electricity and CPU power to extract as the reward for this effort fresh new BTC. This is highly suggestive and seductive. It suggests that an awful lot of effort was needed to find something of value. In fact nothing of value is found. At the end of the effort, if they win the race against other miners, they are alloted new BTC as a simple number in their account. The BTC could have been added without any of this effort. Its a game, an incredibly crude brute force game of trial and error, totally artificially devised to manage the development of the BTC supply. There is no added value whatsoever here, though I will not get on the high horse of the negative environmental value of the electricity usage (after all I am not convinced of that one either
).
