I would sell all my Bitcoins if I knew that in the next day they'll be worth $10.000 and one week later would be worth $300, so I could buy them back

I would sell my bitcoin if the price goes very high 

I will probably sell 2 or 3 when it hits 1 million dollars per coin 

I would never sell out all my Bitcoins , even at $1 million per coin, just a few so I can call myself a millionaire 

I would sell off all my bitcoins if it hit 1Million dollars.

I'm a millioner, because I have millions of satoshis 

I would sell all my Bitcoins if I need something to buy. Bitcoin is just only a type of money for me. If I need to spend, I will spend them.

I would sell all my Bitcoins if the price reach 1000$ again.

I would sell all my Bitcoins if the price went up to $1000. 

I would sell all of my bitcoins if they were worth 50 million dollars and I felt the US dollar was perfectly healthy.  I don't see this happening anytime soon though.  However, if the Fed successfully works with Congress to get things back under control and my BTC were worth that much I would definitely take the cash and buy safer assets.
