I can recommend you to use Bitstamp to transfer your money since you are european. Verfication needed aswell.
There you can buy Bitcoin, Ripple and ETH for a Fee of 0,25%
If you want to buy other coins you need to transfer ETH and Bitcoin to another exchange, where you can buy other coins/tokens.
Please be aware leaving any coins or token on exchanges are risky. Especially the less known and audited exchanges.
Bitstamp is one of the better once since they store 98% in cold wallets and checked regularly.
Not sure if it's worth to put up offline wallets for all the different coins since you are not buying in to much.
Up to you how you want to store them. It is always good to split it up a bit, less risk to loose all.
Good advice. First, choose a local exchange supporting the money exchange to encrypt, such as BTC or ETH, then you can transfer other exchanges as you like. The different crypt's transfer fees varies, and the price of encrypt waves differently, you should count it by yourself.
