No need to worry.
BTCgonna do what BTC does, and we seem to have enough cushion that any of us HODLers should not be worrying too much... and if we are worrying, we have a bit more profits that we could skim off in this $7k price range in order to prepare us for $5,800 or lower, just in case....
Let's say, for example, our total stash is only 5BTC. Let's say that we have been struggling for about the past two years to acquire BTC with every paycheck and upon every price dip. The reality of the matter is that if we really fear going down to $5,800 or lower, we could shave off somewhere between .05 BTC and .25BTC (that is between 1% and 5%) to prepare our BTC portfolio for such eventuality... personally, I would only play with the smaller amounts, but I understand that some guys (and gal) might be willing to risk a higher amount in order to prepare for down... but we should know that we are preparing for both down and up.. accordingly, we have to be able to tweak our holdings, if we are feeling uncomfortable in order to cause more comfort.
I am not always comfortable, but I have sold a bit more than 2% of my BTC portfolio with the price rise from $4,200 to $7,585... Whether I am able to buy those BTC back or not, I remain somewhat neutral in my feelings.... therefore if the price goes down, I will use some of those proceeds to buy back the BTC that I sold, yet if the BTC price does not go down, I am o.k. with that outcome too... because over 96% of my BTC to fiat value remains in BTC...
Win-win situation, I love it! I tried to do the same with a little part of my holdings (about 5%) yesterday, which is totally stuck in Binance for now. Sold at $7400 and thought the same thing,
"if bitcoin goes down, I'll buy back from this USDC bag, if it doesn't go down, I still win with my remaining holdings". But then I bought back the BTC (FOMO'ed at the dump) at $6800 as I liked the little 0.03 BTC profit off that Binance bag.
Yes. That is the idea. A step in the right direction. Usually, I would spread out the buys a little more incrementally.
I also understand the idea of FOMO buying back - because I have done that kind of thing on a number of occasions.
I already tend to engage in a BTC buy back practice/strategy that tends to involve buying back way too much BTC and way too early. In that regard, in the December 2017 bull run, I sold small amounts of BTC all the way up to $19,500 or something like that. And, I began buying back the BTC that I sold (and acquiring more BTC, too) at about $19k, so I bought back BTC all the way down to $3,200-ish.... So it is NOT like I am making any kind of killing with the way that I buy back BTC, based on my ongoing willingness to buy back BTC and to consider that I am profiting because I am accumulating more BTC than I had previously and without injecting more funds.
Let's take your example. of selling in the ball park of 5% of your stash at $7,400. Since you stated that you fear going down to $5,800, you could have structured your BTC buy backs to go all the way down to $5,800 or some price in that ball park. For example, you could have divided the proceeds up into 10 parts, and set your BTC buy back orders of .5% every $100 (between $6,800 and $5,800), or some other variation of that. I understand that your buying back all of it at $6,800 was a bit extreme, even though it was a profitable transaction, yet your "FOMO buy back" did not end up insuring you for the $5,800 price that you are likely continuing to fear.
I am not really saying that you need to do anything exactly right now, and personally, I rarely ever sell more than .5% of my BTC holdings at any one time, and even selling that much, at once makes me nervous. Like I mentioned in my earlier post, it took a movement of more than $3k (80%) from $4,200 to $7585 to cause me to sell a bit more than 2% of my BTC holdings... (and that was more than 15 sales orders.. and I think that my highest sell was at $7,350-ish.. - by the way, I don't set either my buy orders or my sell orders at exact round numbers).
