How should I send my bitcoins to my wallet from coinbase
If you only have 10 euros in Bitcoin, it is currently not worth sending to your wallet. The current Bitcoin transaction fees average around $50 USD today. You can see the chart here. This is because there is an enormous amount of Bitcoin transaction, but only a few transactions can fit in the 1mb block.

If you had much more money, you should definitely send them in a wallet you own the private keys. Some exchanges like Mt. Gox closed and millions worth of Bitcoins were lost. There's a lot of fire right now in the Bitcoin community, so owning your coins is a good start.
