ANY GREAT ALT COINS THAT ARE VERY LOW RIGHT NOW
Okay, so if you are already checking for coins who are listed in exchanges and want to invest to some of them, make sure to take into consideration of checking Waves. They are mainly traded in Bittrex but they are also listed to several exchanges on the web. They have the technology and team that's working for hard for it to progress and many people are looking into it as the next ETH (in comparison with its price run).
On the other note, you can also invest that money to an ICO that I'm advertising right now. Truckcoin provides you a promising project and can provide decent profit after the ICO phase (if it gets successful). Check the links to my signature and see for yourself.
