Guys, please don't learn this the hard way: do NOT ever put your funds on a computer or a mobile application of any kind if you hold any significant amount.

These type of applications can and will be compromised going forward, if network & device security is not up to standards. Use them for holding 'petty cash' only.

Use hardware wallets (they have insane security) to store the bulk of your funds. This way the private key never even leaves the device and your are completely safe.
