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 .
