I sold my remaining stash recently when BTC reached $22.5K which felt great. Chinese New Year could have helped it surge suddenly along with several other reasons like inflation dropping, recession chances dropping etc.
It's good if you are satisfied with your profits as someone selling at $50k can also be at loss while some selling at lower rates can gain more profits but in the end it all depends on how much satisfied you are with your gains.See the main point for me is pumps if it comes from any point as I am long term holder with my coins.
