First question do you really have a bitcoin on hold or to sell?because seems like you making some panicking issue here but the truth is you have no bitcoin on hand
I will hold and hold even if it takes me more than many times,or until my target value attained by this great coin,then i may release all my bitcoin,or maybe i will wait until the whole world accept this cryptocurrency even if not in my time.but my childrens in future
Well people are like this, they can sometimes make the situation much worse because of assumptions, speculations and poor emotional control. For me, why asked if the answer is clearly hodl or buy more coins. It is pretty obvious that at times like this we have options but the very best to do is to hodl and buy. Instead of feeling down because of the dump, we should have a clear mind about this for us to see that there are solutions and things that we can't do so we may not lose more than what we have lose already because of the dump.
