I had to pay a ransomware bill in February 2015. I bought the right amount of Bitcoin but, like many people, forgot about the transfer fee, so some kind person donated me 0.005 BTC. This means once I was done, my Bitcoin wallet wasn’t totally empty. I have just logged into it again for the first time since, and found that the value of Bitcoin has gone up 28x since then, and so that small amount is now worth… £21.94 (US$28.91). I guess I’m an accidental Bitcoin speculator…
