A profit is a profit.

Would you kick yourself more if it went down and you missed selling high, or went up and missed selling low?

There are 361M lot on the sell order between here and 70,  221 BTC.   There are 154M on the buy betweenhere and 20, 53 BTC.

Depends how many sellers will decide to take a profit and sell lower imho.  That also depends where they bought at though.  There have been many millions bought at 60-50 so those people will either decide to cut their losses or now become long term holders.  If they were going to cut their losses, then they would probably have done it by now imho.  There is still a fairly meaty buy order in the low 40's.  would take some serious selling to breach that imho, and thats when there may be a quick panic from small holders that got in at the 13-15 prices last week though doubt it would be enough to do much damage though - and those who bought at 60 would just buy more on the way down to keep averaging down (if they have the funds).
