Thank you for youre answers!   But did you all notice, that bitcoin.de isnt "a normal exchange", its an exchange 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.

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.

Sure, hardwarewallets and paperwallets are the safest. I protect the large part (about 83 %) of my bitcoin in a hardware wallet (maybe it would be clever to buy more hardwarewallets and to devide my bitcoin, what do you think? ) and a small part in an Onlinewallet (about 8%) and other places (about 9 %). Is that "good/safe enough"?

How do you protect youre bitcoin/crypto?


Thank you very much for youre answers!!
