If Jaxx is not save, then does that mean all the mobile wallets are insecure? Then where should i keep all my coins?
I think jaxx is safe i have used it for long time to saving ethereum on there, but still there are risk losing the digital coins on there, so i also used mycelium on android smartphone devices, jaxx to saving the altcoins and mycelium to saving the bitcoins, actually there are no guarantee our funds is safe in mobile wallet, so never put the digital coins in one devices and always do back up the private key.
Eth or Etc? The Classic one had an issue a while ago and don't know if that was ever resolved completely or not.
