I see! Thank you for the break down, meaning I shouldn't be using MEW or trustwallet anymore?
Any advice you receive, don't trust, let's verify it with other sources like this tool.
https://walletscrutiny.com/Good link, forgot about this for a while. I think people need to do this more often. Cold wallets that are closed source, I just can't bring myself to trust.
But another important advice I think is people really need to test 1 or 2 cold wallets. You know if you're keeping a few hundred dollars of altcoins, and the cold wallet or cold technique is soooo hard to use, I think people are oversecuritizing.
Nothing wrong to keep even a simple wallet on a cold device to start with.
