Exactly, when you sell and indeed to buy back at a cheaper price you might end up not buying back because of so many reasons, which we cannot predict the outcome of what would happen by tomorrow. If you sell to buy back, it destabilize the purpose of investing and increasing your bitcoin portfolio. Patient does not have any role to okay here, because you are waiting for a time that you don't know when the price will dip for you to buy back, and you keep waiting hodling fiat that is depreciating in value.
yeah alot of users are used to such act selling from their bitcoin holding with the mindset of replacing it , one thing you should be Aware of is that most time you won't have that privileged to buy it back that same price or cheaper price ( if one wanted to replace back) , like for instance now alot of users bought bitcoin during the time Bitcoin price was Around $10k , alot of users sold from their holding with the mindset of replacing it back, at the same ( they brought it) or much lower price, but look at now bitcoin already around $70k and alot of people who sold like $500 worth of Bitcoin during $10k which would be
0.5 BTC . And lateron replace it back ( with $500,) during the price range of $60k which would give that same individual 0.0083333 BTC . You can see the great different. That's why not advisable to keep withdrawing from your investment even one having such mindset of selling with replacing it back .and we are all aware that those that started their bitcoin accummulation would be in more advantage's than those that invested now .
That is a fair example, except your math is wrong for the guy who sold
0.05 BTC at $10k (which is the equivalent of $500) in order to buy back cheaper, but he was not successful.
Another example of recent times is that there were probably plenty of guys selling on the way up from $27k to $50k, and they were expecting to be able to buy back cheaper, and they may well not get any opportunities to buy back for cheaper than they sold, and at some point they may well have to suck it up since patience is not likely going to be enough to actually get an opportunity.
And, some of those kinds of folks who sell way too much too soon because of their expectation to buy back cheaper, they get into a pretty lame, negative and disgruntled mindset.. All because they thought that they were being smarter than everyone else.
We should understand and appreciate these examples that when we get 10-15 years down the road, we are likely going to be in a much better position in regards to our BTC stash and our overall wealth because we had continued to stack sats through thick and thin and even if our costs per bTC might be higher than otherwise, we may well end up accumulating way more BTC because we kept the right mindset of an accumulator and a sat stacker.
