This is really my motto. I care about not missing any of the dip levels. And I think that it is really important for a HODLer. In the long run, I know that I will make a really good profit. I just need to keep being patient.
That's like the standard for a hodler in the first place, they should be able to hodl bitcoin for a really long time. Getting in the dips is just a bonus for long-term hodlers to accumulate at a really low price.
Long-term holders should have sold Bitcoin when the price was above $50000 or $60000,
of course holders would also know when to sell it, or maybe 50% of the assets they have sold,
and that's a strategy that we should follow, if a DIP does occur. we have to do accumulation,
otherwise it is something to regret.
The idea of buy every dip and HODL does not include any kind of selling strategy, and personally I believe that it is NOT a good idea to be trying to sell BTC or to time the top, at least until you have reached or exceeded your BTC accumulation goals, and maybe that is what you are trying to imply when referring to what you believe "Long-term holders" should do or try to do.
Even long term HODLers have sometimes NOT met their BTC accumulation goals, and in that regard it could be quite problematic for long term HODLers to be playing around with selling very much of their BTC stash.. of course, selling small amounts or shaving off a bit in order to feel more comfortable to be able to buy back upon a dip is not a bad thing, but it seems that any person selling small amounts has to realize that the BTC price might not come back down for them to buy back, so they need to be careful in terms of expecting it to correct and even how much they expect the BTC price to correct.
Furthermore, if a HODLer is a long term enough HODLer, for example buying his/her BTC in the $500s or something like that, then s/he might not give too many shits if s/he wants to buy something for let's say $10k, and he could have sold 0.154 BTC when the price was $64,895 or now s/he has to sell 0.2857 BTC in order to get the same $10k. So of course, if you hold your BTC long enough, you might not get too concerned about when you sell it exactly, even if you might try to sell when the price is higher, but you are not going to get too worked up if you end up shaving off the amount at a less preferred time, such as when the BTC price is $35k.
