I can say taking profit is always right, but if you are thinking of selling bitcoin and then switching to altcoins, then I suggest you stop. It is true that altcoins will offer higher returns than bitcoin, but the risks are also more significant. You also saw 2 crashes of the top 2 altcoins in 2022, and you made a wise decision to invest in bitcoin, not altcoins. You should keep your stance on bitcoin and DCA instead of shifting your investment to altcoins which are not recommended even if those are the top coins.
