Of course, I think most of us are buying altcoin at the dip and sell it every time the price bounce back to the resistance. I think you should take this opportunity to buy undervalued altcoins instead of panic sell every time the price goes down. If you don't have any money left then I recommend you to HODL your current bag and until next year to sell because short-term doesn't look very good right now as the trend is bearish.
