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.
Indeed I wouldn't sell yet not even at this point cause there is alot more potential to be taken out of bitcoin.
Wait a few years 5+ and we will see where bitcoin will go and how high. I foresee a bright future for it though.
