in my opinion is not an actual problem or not, but sell for a loss or sell for profit. or other possibilities you feel disappointed because in a few months bitcoin prices move higher.
It is your understanding that you want to do sell during the dip or want to sell during the high and make money it all depends upon you and your future vision. If you believe it is a bubble you will always end up in a loss as always during dip you will sell and after some days prices shoot up .
