But what was your purpose of selling BTC?  to buy back lower?  or did you have some kind of consumption/investment need for the money?  or was there some other reason?

Many members here know that I have been systematically selling BTC as the BTC price goes up since $250.. so of course, my whole system does not sell so much BTC as to really undermine my overall BTC holdings, so in that regard, I am not dependent on buying back in the event that the BTC price does not go lower than whatever my various established sell prices had happened to be - on the other hand, if the BTC price goes down after I had made whatever sales (on the way up that I had), I use the sales proceeds money to buy back.. those amounts are pre-established too... .so for example, these days the buy sell orders are about a $6k or 7k spread.. so with the passage of time, the buy back spread has gotten larger and larger, both in terms of substantive value and also in terms of percentage difference too... .

On a related topic, yesterday I discovered that about 6 days earlier (on October 29), I had made a mistake while I had been setting BTC sell orders in $3k to $5k increments between $100k and $150k, and I had accidentally sold some BTC at $62,500-ish that had been meant to be set for selling at $116k-ish.

In essence, I am describing a mistake, so whenever I discover that I made a mistake in setting my orders or maybe accidentally buying or selling (as happened in this situation), I will thereafter attempt to recover from such mistake (and even attempt to profit on it - even just in a small way if possible or if the BTC up and down gods are in my favor), so of course in this kind  of a situation, I have to either attempt to buy back the portion of BTC that I had accidentally sold at a sufficiently lower cost in order to cover the back and forth fees and/or to supplement my buy back orders in such a way that might be less preferable but ends up being a kind of mitigation of damages by  cancelling (or reducing) some of my BTC sell orders that had been previously set at various price locations higher up the ladder of BTC sell orders.

I guess what I am also saying is that based on such mistake, I have made an effort to rebalance my BTC buy/sell orders in such a way that I remain as emotionally neutral as I can be in terms of which direction those buy/sell orders fill... and sooner or later they are going to fill because there is almost a zero chance probability that BTC price will stay ranging between my price points forever and ever (even if sometimes two weeks^tm might feel like a long time).
