I cannot suggest my exit price of bitcoin for this bull run at the present moment because no one is sure how high will it go. I think when you see a parabolic move like 20-25K upward movement in a day or two, you should be caution because all bull markets are most parabolic at the end.
It's really hard to determine, you want to satisfy your greed because we have waited for a long time to make a profit, we have a long bear trend and we want to sell at the highest possible time, and we don't want the bear trend to stop us, it's better to sell a little portion and if there's a correction, take that opportunity to buy again.
