You can do what you like Victorybit1, but it does not seem to be a good idea to be fucking around trying to sell and buy back cheaper, especially if you still have a goal to keep accumulating bitcoin.
One of the best ways to assure that you keep building your bitcoin stash is by keeping on buying, so selling is not a good way to increase your stash.
Sure, the more bitcoin you accumulate and the longer you are in, then you might start to think that you can time the waves, yet we have a whole hell of a lot of examples in bitcoin's history where guys end up selling too much too soon and they also end up not accumulating as much bitcoin because they are too busy waiting to buy on dips rather than ongoingly buying.
You are right sir, and all that you said here are very true, selling with the hope of rebuying it back is not the best way to go about your Bitcoin accumulation because you might likely sell off too soon, and that price you sell thinking to buy back may be the lowest price that person may ever encounter again.
Those investors that sold their Bitcoin at $72k thinking to buy back when the price of bitcoin goes deeper, how would they feel that moment that Bitcoin keep on rising to $124k?
They will feel really bad for themselves because they themselves deprived themselves from an opportunity they would have benefited from, so victorybit1 stop trying to sabotage your own effort by selling thinking to buy back because bitcoin can do the big jump in price it usually does, and you may likely miss out, a word is enough for the wise as the saying goes.
