As many of the members have speculated here, the 30k$ support is crucial as well as psychologically important. If that breaks then it will be a Dejavu situation for some holders and they are probably going to sell in order to get back in when there is a bottom. In my opinion, I don't think that BTC will break that support. The feeling is strong with Bulls and we might see a run sooner or later.
It is always risky to sell off the coins and think about entering at a later time unless we are in a complete bear market. Right now we are having good support at $30k and hopefully it will be like that for a long time and for over a month we are trying to break the resistance at $40k and if the market is like this for a while and if there is no major sell off then the market will attempt to touch the all time high valuation before the major correction.
