I am still holding on my altcoins, not a good time to sell it now. Ive sold a few last year when the prices are good and still selling some only when I need money. I am still buying altcoins if I see a good opportunity, especially when the coins are cheap. Im holding until the end of the year or until the prices increases again. The altcoins I am holding aas of now are etherum, waves, wanchain
