I am primarily a long term holder. Sometimes it is a good idea to skim profits off the top but not advised unless its needed. Everyones portfolios are down today. You will start to see the ALTs come back. BTC/ETH/LTC are still down 15-20% so it will take time to bounce back. My best advice is to relax and not check it for a few days if it is stressing you out. You will be rewarded for your patience.
