Do your own research on these coins before investing.
I want to test community ideas for my play money, and this limits my research to just a few.
I would suggest you to check out UBIQ which is an advanced version of Ethereum. It's at a Good price today.
Ubiq is up 100x this year already. I think it is risky to jump the train now.
Aragon: This coin is good for long term.
Aragon has a nice price development without sharp jumps up.
If you give me choice among waves, litecoin and doge then I would pick Waves at first and litecoin next.
Waves and Litecoin are both going up now. I can get one this week and the other one next week.
