Wow, how do you not know about altcoins for a forum member that has been in the community for sometime now. It's quite offbeat but nevertheless there's nothing wrong about your questions.

Before you get to invest in any altcoin you have to do some analysis about the very coin and not to invest blindly on any coin as the aftermath could be very devastating because of the high volatility of altcoins.

I think instead of asking from other members about what altcoins to invest in right now, you should rather invest some quality time to learn and study the altcoins market and build a background knowledge about the developments of these altcoins and their backing.  What's the best coin for X may not be the best for Y, but it's when you have knowledge about the market you understand better why the bias that exists.
