They happen every couple years. Enjoy it.
Do you talking about the current price for bitcoin, right? That's a real break to bitcoin I think. I saw on exchanger they have 978$ per 1 BTC. 1000$ is crazily near. But how to enjoy this times? To sell bitcoins or to keep it, cause the grown will be continued?
I am 100% certain with you, because i also confused about selling or holding the bitcoin, even i also don't know it is time to celebrate or wait for price increasing more and more. Now i have sold my 2 bitcoins and still i hold my 2 more bitcoins, but every time, i think may be price will be more increased, that's why i have been stop myself and look the speculation about bitcoin price.
Depending at exactly what price levels you bought and sold your coins at, you most likely have done well. If you sold at current levels where you made a more than decent profit, I would just wait out the market reaction at the time the price reaches $1000 again. Selling more is not smart as literally anything can happen. You'll benefit anyway. If the price goes down, you'll be able to buy back at lower levels. If the price goes up further, you'll be able to cash out even more profits on the way up. Just make sure you always hold at least 1BTC that you will not sell.
