Loosing your bitcoins due to a glitch on your mycelium app, and how do you get the back without a backup? I went and purchased some bitcoins on my mycelium wallet. Once I went back to my car and opened the app to do a backup for it the app just stopped working and it wouldn't open back up. I couldn't do the back up to it, so I sent an email and asked if I uninstall and reinstall will I loose the coins that I just purchased? it took them an hour to respond to my email and by that time I had already uninstalled and reinstalled my wallet. The coins are gone but I looked up my transaction on Blockchain and they are there. How can I recover my coins when Mycelium had the glitch (that was fixed with an update) and there email was an hour late to respond to my question, how can I recover those coins?
If you do not have a backup of the wallet, either in the form of seed words or a exported file from Mycelium, then your coins are permanently lost.

Ideally, one should be backing up and restoring their wallet to make sure they've got all the necessary information before sending a significant amount of coins to it.
