Bitcoin avant la lettre
The first known (to me) attempt at cryptocurrencies occurred in the Netherlands, in the late 1980s, which makes it around 25 years ago or 20BBTC. In the middle of the night, the petrol stations in the remoter areas were being raided for cash, and the operators were unhappy putting guards at risk there. But the petrol stations had to stay open overnight so that the trucks could refuel.Someone had the bright idea of putting money onto the new-fangled smartcards that were then being trialed, and so electronic cash was born.
