That is if you have a goal of short-term which is going to be different from those that have a long-term goal like @virtualdn who has been hodling for a long time. I did get my share of profit when I sold above 50k so I don't mind hodling for a really long time on this one.
Good timing for you if you managed to sell your asset during that period, the market still volatile
and without certain goals, your chance to bring something out from the market is really slim, you
need to point your target and make sure to have a good overview of the incoming market, from that
point your chance to sell with good value is very high.
I have been hodling those bitcoins for about 6 months back in March so I might as well earn some money out of it because it's not like bitcoin is going to go up forever knowing that it's as volatile as it was back then. You are right that you should make a goal before selling because without one, you will get lost along the way.
