650 sell 30% of my bitcoin, waiting for 600..

Really? Good luck with that. I'm pretty sure it will not go below $640 anymore. And especially not below $630

We were below that just 30 hours ago, and we are at $646 right now! You're "pretty sure" that it won't drop 0.9%, EVER?

I'd give a good 80% chance of it going anywhere +/- $100 from the current price for no other reason than volatility!

Agreed!
