There is no how you can take profit without selling your bitcoin, assuming you bought $50 worth of bitcoin and the price doubles, then you want to take profit and keep the capital all you got to do is to sell part of your bitcoin that worth the amount of profits you want to take and leave the rest, that the only way you can take profit, you can't eat your cake and have it back, if you don't want to sell then you don't need to take profit.
Well, if you just know about staking, maybe you don't need to sell your Bitcoin for the sake of making a profit. In fact, this was already been used by many and the profit is good but never it thinks that really give you a huge profit, unlike trading. But the good thing about staking is that your funds are safe provided that you are using a reputable site. But also have to keep in mind that putting funds in the exchanges is also at risk, so it was best not to hoard big amounts.
