Im surprised there is no bitcoin and ethereum on your suggestion.
My surprise was short-lived, seeing that he was in a bounty campaign for a known scam as bitwings...

Anway if you are gonna suggest why these coins to OP better give him some information about these coins cause he is asking about it. No sense to recommend when you dont have information why should he invest on these.
I would suggest to the OP to do the same thing as I did, if a user suggests him a coin, even he gives a lot of information about to check how much of that is vaporware and how many shilling for some coins that will turn to dust in a few months. If you're new to investments start with the things that have been at least close to solid in the past and with a history, don't throw yourself at the first opportunity, yes you can hit the jackpot but you can also lose everything and the second happens more times than the first.
I'd rather suggest using those 500€ in day trading. It's not as safe as investing in top 10 coins but with good management and the right skills, you can make a good profit out of it. no risk, no reward 
Don't do this! It's like rushing people to gambling when they have no idea how odds are calculated.
