As you can see BTC face 50 period MA and at this time hasn't strenght for break this MA so price seems to have formed a simple double top. The measure of this double top is calculated between the arrow marked on the graph and the amount is 2474 points. If you subctract this value to the neck line of this double top you reach 7000 usd area where pass the green line started since 2017 july where BTC reacted last time in 2018/2/06, so probably we may reach that level for having a strong reaction. As you can notice I traced red vertical line to mark key points where green line is originated.
