Bitcoin target can be seen near term at $1700-$1800 range. So, better take profit and keep patience to buy again. The pattern it is made by bitcoin trade today is bearish.
So, I will suggest to sell at this level and buy at close to $1700-$1800.
The fundamental of bitcoin is now more competitive to peer as well.
This sell off may be due to profit booking. On the other hand, Ethereum is also a good bet who is giving competition to Bitcoin.
The transaction fees is also high in Bitcoin.
