I had bought about $50 worth of BTC a year ago and it's now worth $800. Did the bitcoin economy grow that much in the last year? I've heard of increasing adoption by banks and governments but I don't know to what extent they're investing. I don't follow it closely and at this valuation, I have no idea whether it's a good investment or not. Should I sell it now before the inevitable crash? Should I buy more? I don't trust myself to understand this kind of speculation yet.
