Today there is a correction that is around 3% and makes the price drop below $ 25k, of course many are worried that the price will continue to drop and below $ 20k, this proves that the strategy to sell immediately when a profit is at least 10% is the best way, We see whether Bitcoin can return to $ 30K this month or not.
You also only saw the drop in the space of one day because not long after you saw the drop, the price of Bitcoin slowly made its way back past $25K again although it still looked quite difficult to get to $30K. I'm still pretty sure that Bitcoin can surpass $30K even though it might not happen this month, but in the next month it is still possible for it to happen as long as price improvement continues in the market.
And for the sell strategy when you see a 10% profit on Bitcoin, I think it is only used by day traders or short term traders because maybe they are afraid to keep Bitcoin for a long term, but if you yourself want to run such a strategy also not a problem because it depends on the wishes of each person.
