I don't understand people like you. We were in the ~250$ range for a very long time after which the price went to around ~450$. This sudden rise is not something that can ever be stable. It has to correct itself (i.e. come down) from time to time. Last night Bitfinex was down for a few hours as far as I know. That could have been a contributing factor (as the people there were losing money not being able to trade, while other exchanges were going down). You should not be looking to solely profit, and know by now that this is the wrong section for price speculation.
Yeah, we can afford to wait longer to earn higher profits, as price is not too good at a moment to sell as it will not allow you to make higher profits.
Bitcoin was meant to be used not "wait longer to earn higher profits".
