I tried to research and can't find any way to do that in any of the exchanges I use such as kraken, bittrex or coinbase.
The only way I know of, to take profit of bitcoin bull run is to sell some bitcoin which means the bitcoin holding will reduce.
So, I am just wondering is it really possible to take profit without reducing bitcoin holding? Am I missing something here?
Doubling your money is possible, but taking profit without selling your bitcoin is not possible. Check those that invested at the price of 10,000 USD , they have made four times that amount by selling at 40,000 USD, so it’s possible to get more than double the money you have invested if there is a bull run.
But saying that you can take your profit without selling your coin sounds unbelievable, unless you’re keeping your coins and taking the profit from another man’s pocket. And moreover, if your investment grows and you don’t sell it to take profit, you’re going to lose that money when the price falls.
