When is it over? End of the year most likely. The second bull run already put incredible effect over the market, I guess everyone thinking same. This move is surprising however this is the fact. Bitcoin maintain the price quite well and investors still buying. The red and green arrows indicates where you should sell and buy. BTC had been on fire however specialized recommend a draw back.

Support is completely obvious in this case. At least maintain the major support zone indeed very necessary to secure further developments. Anyway, the recent BTC movements we can expect a pull back.
