The highest I ever paid was ~$510/BTC for about a third of a big one.
Bitcoin is supposed to be for everyone, not just the wealthy, so are you comfortable spending $50 (for example) for less than 0.1btc?
Have you ever paid more than $700/BTC for any amount of Bitcoin?
No, I have not. That's simply too much money for me.
If I won the lottery or something, maybe I will.
