Hello, if i leave my PC and someone can acess my wallet from it and transfers my BTC to himself, would i be able to get those coins back if i have a made a backup of the wallet and saved it on another USB for example? Or how can i be sure i can keep all my BTC safe without someone else being able to get in contact with them?
This is just a WORST case scenario. Will most likely not happen.
Thanks in advance.
No you can't get them back afterwards.
Encrypt your wallet so people can't have access.
