That's what I checked out first and I tried the sweep but ran into some error like code 4 and looked into some resources but can't seem to identify what the problem is and my next question will be about that but meanwhile, I tried some basic like sending/bump fee with the coins got from faucets.

And one coin per QR? That's overwhelming for me.


I get it, but why are some people doing that when the testnet coins have no value.

I will add the link to the first post.
