Pity our tiny little brains. For some reason that escapes us now we thought it would be jolly interesting and not at all SODDING BEWILDERING to attempt to understand Bitcoin. That sobbing noise you can hear? That's us.



Why? Well it may *look* like a harmless bunch of nerds sending each other made up money over the Internet, but it's also playing a not inconsiderable role in knackering the planet. With 1% of the world's electricity - and rising - being spaffed on cryptocurrencies, we thought we should at least ask: right, what the bloody hell's going on?



Is Bitcoin contributing anything useful at all to humanity, particularly given - y'know - there's a climate crisis going on? And whatever would Dr Emmet Brown make of it?
