Yeah, I'm not certain what it means about the fees being later maliciously adjusted.

Seems strange.

Does it mean.

A. If you had 10 bitcoins in your wallet someone could charge the entire 10btc in fees
Even though only want to send 0.01btc to the recipient and want to spend 0.0002 in fees.

B. That when you have signed it to allow 0.01 btc out of your wallet then it could just use up that entire amount in fees.

I dont actually know what it means.

I dare not test it with a small tx because it may mean it can absorb the entire balance and use it as fees.

When you look at a raw signed hex in bitcoin core wallet with the decoderawtransaction command.
Where do you see the fees?

I can only see the vout for the recipient and change.
I don't see on the bitcoin console where it shows the fees.

I believe someone said you can just calculate that when you take the recipient and change from the balance.
But on electrum it shows the fees in the console expressly.

I'm not sure why but the yellow triangle just seems to be worrying.
It says it can only be maliciously changed until signed. But I'm signing it straight away.
