Just sent mining money from my Zencloud account to my Electrum BTC wallet. I seen it start to confirm in my wallet, and everything was fine. I go to send the BTC from my wallet to an exchange and suddenly the BTC is not there, the TX is not even showing in my history. My wallet is encrypted and i've never had anything go wrong before. How the hell does BTC just start to confirm, then all of a sudden, disappear? This has me extremely anxious and upset. Will it show eventually? What the hell is going on??
