This is a hypothetical question. I am wondering, can my desktop wallet be hacked if I log into an unsecured WiFi hotspot even if I do not log into my bitcoin desktop wallet? I am wondering because I travel a lot, and when travelling I sometimes log into coffee shop WiFi hotspots. I don't keep a lot of funds on the desktop but I'm wondering about this.
as long as you can save your private keys and not giving the password to other people, you can feel safe. i think you can use another wallet if you want to protect your bitcoin and you can buy hardware wallet too that will give you more secure. i don't think that someone which have more than 3 btc will saving his bitcoin into desktop or android wallet because today the bitcoin price is not cheap. if you are connect with unsecured wifi hotspot then you might be need to activate your antivirus so if there is any intruder that want to hack your computer, the antivirus can give protection to you computer.
