Now is the time to buy the dip and fill yer bags.
It's probably not over yet.
I would say that the market will always over adjust, and right now it has adjusted, though still probably not quite enough. i wouldn't be surprised if bitcoin were to go down to a level that is say, $1800,$1900. Something along the lines of that.
When it does happen, as you said it'll be a great opportunity to buy in.
Always go against crowd sentiment.
People who
always go against the crowd sentiment end up getting destroyed by the market, since crowd sentiment is essentially what determines what is successful and what is not in capitalist markets. Every market is just the expression of crowd sentiment. The crowd gets irrational from time to time, which creates opportunity. But opperating on the assumption that the crowd is always wrong is a recipe for ruin.
I think that what he meant wasn't really crowd sentiment, but rather when everyone is pumping up the price of bitcoin etc., you should dump all of your coins, and when everyone is saying that bitcoin is trash, it has no future etc., then that's the time to be in some for holding.
Honestly you'd be surprised at how many stupid investors that are out there, and how many instances someone could have dumped their coins for a nice chunk of money but instead wanted to make more and got greedy.
I do think though that there's probably going to be another dump somewhere soon in the near future. How much it adjusts by, i'm not particularly sure but the pre-fork panic is going to affect the price of bitcoin negatively imo. Altcoins will be dragged down alongside btc, though some might actually get pumped as a hedge against btc(ripple, eth). It'll be a good time to buy at that stage.
