Thank you for youre answers!

But did you all notice, that bitcoin.de isnt "a normal Onlinewallet", its an Onlinewallet with a lot of security mechanisms. This Onlinewallet even has got an own forum and they claim to be one of the safest Onlinewallets worldwide.

bitcoin.de is not even a wallet, it is a trading platform so it is a place where you should only go and buy/sell bitcoin not store it!

So in conclusion the safety of the Onlinewallets might be a little bit lower than I mentioned, but its not close to 0%! For example bitcoin.de never got hacked and the site is over 5 years old! The guarda wallet is relatively unknown and so I dont think, that it wont be the first target for hackers, right? To be unknown is a way to be relatively secure too.

hundreds of users lose their money every month because they store it in a web wallet and lose it to all sorts of attacks including but not limited to phishing attacks, malwares, key loggers, ...
in addition to that when you are using a web wallet that doesn't even give you control over your private keys then it means the security of it is 0%.

(maybe it would be clever to buy more hardwarewallets and to devide my bitcoin, what do you think?

it is an overkill in my opinion.

and a small part in an Onlinewallet (about 8%) and other places (about 9 %). Is that "good/safe enough"?

the only usage of web wallets should be for convenience not security. for example if you wanted to keep some small amount like $50 worth of bitcoin in a web wallet so that you could access it (like to do a purchase) from anywhere without having to carry anything with you.
