I have around 1,7k Hive power currently and my personal goal is to reach 2,5k Hive power. So before I reach that amount, I would not sell anything.
If I got over 2,5k let's say to 3k Hive power and then Hive goes to $10 I would probably sell 500 Hive and then get back to collecting without watching the price again.
Only because at my current spot in life, I could put 5k$ into really good use :)
