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?
Yep...I have bought (and sold) above $800. Also purchased for family who have patiently waited for 2+ years for it to get back to their original purchase prices. Hopefully in another month a two the price will be way above what they paid and I won't look so bad.... lol
