I'm new here, but you buy any alcoin you have to know much about the coin before investing on it.
It's a good time to buy altcoins, the market is under the flow, the prices of some altcoins are affordable as they are posted on the market. Some considerations must be considered before buying the coin, such as Market Fundamentals, Market Structure, level of Confidence by investors for the alt coins, and of course the amount of investment that you will enter, both for short or long term investment.
