Previous monthly close was the most bullish monthly close in bitcoin history. Even in december 2017 when bitcoin has reached 20k monthly close was still lower - 13716. Apart of historical close, monthly candle is very optimistic itself - strong pump without any noticeable wick on top.
In many our previous updates we have been saying that a break of 2019 high - 13950 should 100% trigger bullrun, and during weekend bitcoin has finally cracked this level. Even though price has dropped after that still technically it doesnt matter, but the fact of a new high matters.
By no doubts bitcoin will keep going up and bullrun is just beginning. If you wanted to buy more bitcoins but had worries that its not a bullrun but just another test of 13000 zone resistance, stop worrying now and buy BTC.
