I bought at $4 with the knowledge that it could hit $50k a coin in a relatively short period. But I sold most of it anyway. In my mind the odds of bitcoin being banned go up every day. People on HN underestimate how much we rely on the financial system to enforce regulations. Governments are not going to just give that up. It’s lasted longer than I though it would, and it might last forever if there is a way to get regulators involved, but 7 years ago I estimated that at 5% odds.
