There are good altcoins in the market right now. Tron, Bulwark and VeChain are some of the altcoins i have invested. Most of the prediction sites are also expecting a good growth for such coins. check out this: http://coinpriceprediction.net/tron-price-prediction-trx-forecast-2018/ they are expecting a good growth for tron. I hope altcoins which has good technology will last in the market. I Personally think BCH and other fake Bitcoin spams will be a huge risk too.
