I am not a financial advisor disclaimer.
All the altcoins are down. There are a lot of alterative coins to buy for long term. Wait until the market settle down before purchase them.
Here are some top picks.
KMD - komodo - A great privacy coin with strong community and team behind it.
ANS - Antshares - Still at the early stage if the project. Name change to "NEO" and some great features are on their way. It can be very huge in China in the near future.
DGB - DigiByte - Breaking into some of the most popular online games implement in games' currency.
This is for open suggest.
