Check the market and looking for on coingecko website to know which one your coin have value and where is the exchange market to sell, I think any your coin above like bitcoin gold, verge, komodo, zclassic, zcsh have market and look good price for selling right now. I think if you have assets coin better to install application bituniverse to know with your coin price, I use this app and always check every day which my coin bookmark to know how much price today, have higher price or still lower price and some time I make alarm when my coin saving raise to higher price I get notification on my mobile phone then I can sell or keep holding. I think is good ideas if you have any assets of altcoin in your wallet without have to check market every time.
