> steal my bitcoins from my 3rd identity wallet (mgh4VjZx5MpkHRis9mDsF2ZcKLdXoP3oQ4) to your own wallet ;) If done successfully, the 3rd wallet will show “Final Balance” of 0. At the time of writing this is 0.00095000 BTC, as we intended and expected.

Can someone explain how this was executed?

You have the secret key, just sign away the txouts.

Guessing it's because the private key is right in the code:

>secret_key3 = int.from_bytes(b"Andrej's Super Secret 3rd Wallet", 'big') # or just random.randrange(1, bitcoin_gen.n)

(Obviously a private key intended for actual use generally wouldn't just be some ASCII bytes of an English phrase and wouldn't be posted publicly. Though, of course, there have been instances of both...)

0.00090000 BTC moved 0.00005000 BTC Fees Thats 5.55%

On the test net! On the real net it would be like 20% or more in fees.

Fees are dictated by the user and the time they have for the transaction to take place. The fee could have been much lower.

I think we are well past the point of debating if bitcoin layer one will be used for day to day transactions however. A custodial service or lighting will have to be used for that. Additionally most people treat bitcoin closer to gold than a dollar currently.
