Why i have to sell everything ?, i can sell everything but i need good reason or good economic opportunity if i see that i can sell my everything for to make more money.
This is not the best time to sell everything and if you do then you are missing an opportunity to earn higher profits at halving, best choice would be to hold your coins till halving.
of course its not the correct time to sell your bitcoins, i doubt that it will be a good idea to sell your bitcoins in the future because in my opinion it will grow for sure
i think i will never sell all my bitcoins because that would be just a bad decision to make if you want to benefit as much from bitcoins as possible then you should just hold and thats it
