First off all thnx for all ur opinions but im not actually looking into which coin to buy thats his decision. I would definatly pick some other Coins. I told him Bitcoin, etherium and Litecoin but he wants to take a risk with a smaller coin with a possibility of a bigger payout.

What I am realy looking for now is how to do it? It doesnt mather which 4-5 coins... Its the method behind it. I wanne know if my idea how to do it is solid and and tips on that process would be much appreciated!

My idea how to handle this is:
-----------------------------------

1) Fiat deposit on Kraken (euro)  - He will be Tier4 approved in a few days
2) Trade Euro To crypto
3) If Oné of the coins is not available trade Crypto wallet from kraken to bittrex and buy the other coin
3) Send to wallets
4) Safe them on paper, ledger, key whatever specific coins is the best option to keep in a safe


Also the ideas you guys suggested about wave, golem, amp, etc i will tell him to look into it.
