I've invested 200 Euro in Bitcoin, Ethereum, Iota and Ripple + 30 Euro in Monero from mining at home.
Current profit (after 3 weeks): 170 EUR (yesterday) / 120 EUR (now)
I use Coinbase for buying and selling BTC / ETH <----> EUR (ID Card verification necessary).
I use Bitfinex for trading / investing in other coins (no need for verification if you're not dealing with USD or EUR).
