Thank you all for the answers.

I just transfered 350 EUR to my Kraken-account. Also I created accounts @ Bittrex, Cryptopia, C-Cex, Lykke Exchange and Poloniex.

It's only 350 because it doesn't hurt me when I lost some of it, also I feel better when using a small amount for first time trading.

Now how to proceed further? Which software is recommended?

I would like to create a portfolio with 2-3 cryptos for long-mid time investment and 2-3 for short trades.

For long-mid term I have BTC - ETH - LTC - XMR  --- which one would you prefer?
For short term trading I'm not sure, but maybe NXS, LYKKE, WAVES, PIVX, DASH, STRATIS, FTC, TORCOIN

I would be thankful if you can give me some advice which would fit the best for now.

Thanks in advance,
Mareksh
