The dump will intensify as we hit $700. People have had a few days to think that $700 is quite a good price to have for the excess coins.

So, where do I set first buy when I go to sleep in a couple of hours?

Think of the
value.
If you value bitcoin more than other things, just buy now. If you would
like to have more coins but don't
mind having some other things as well, select a suitable buyback price.
My buying range is $300-$500 but obviously I haven't set the bids yet because it would look bullish on charts.
