first of all Good Luck with this trade and its really high risk but i need to give my opinion in this
i cant change my mind into btc !! actually it can go further more up by doing small corrections as the Fomo controlling traders .. but as TA i cant lie and say that this Scenario is not valid .. its the most scenario i am convinced that it would happen after counting all waves and sub-waves!!
0.382 Fib levels which is most places btc likes to retrace is the legit point which wave 4 has ended >>> EW rules (correction mostly can go to the 4th wave lowest point)
Extension could be go more down to 0.5 fib
so if u want to short this you can but with small leverage up to 5x and stop loss above the 4217 area which is the start of the correction waves
Targets on chart
Best of Luck
