Why didn't you reply to my question ? would the api key act as bitcoin private key or not? you could spend the btc with your api key.
I did. I will use shorter sentences from now on.
My reply was in my developed post. I will be more straightforward.
No, because I cannot import your API key to Bitcoin Core.
What you claim could be compared with saying that your credit card pin code is your bank account number.
Is it ?
The major and less subtle nuance, is that if I hold a private key, I am the only one to be able to spend the
BTC.
If I hold an API key that allows me to spend funds on a
BTC private key, then myself and the API operator can spend my funds.
This is all it boils down to.
