That’s exactly what I like to do as well. I sold Leo all the way up to 5 hive. I think it was about 25% of my holdings. I recently was able to buy Leo back for 0,89 hive during the hive pump.
But yeah, dummest thing to do is sell all at once or buy all at once.
RE: When the price of the tokens you hold goes up 100x+ within hours, you'll test yourself...and your limits. Can you handle it?
