It depends on when will you need your money. If you need fiat urgently then take some part of your bitcoin or alternative coin. You should practice scaling. But I suggest that you hold as long as you can because bitcoin is on up trend. When the resistance break, it could be rose.
Waiting and holding is the right thing to do. Wait for a short time as the price decrease. Its good to use the opportunity and buy as much possible than selling to grab the profit.
be patient and hold always end well. but you have to be sure about it, because if not sure you will feel free to immediately sell it when the price of a new improved a few percent. I have a lot of experience, and I often feel sorry when I can't wait. so every coin that I hold, I have to have high confidence. so I can be patient and selling at high price.
