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.
Connecting to unsecured public hotspot is so risky there is a lot of system that can apply to router and record all your activity including your bitcoin transaction. Best way to do is bring your own pocket wifi or use your mobile internet if you are making transaction with your wallet.
