Hello!
A quick update to say that I'm still keeping an eye on this transaction, and I'm not forgetting it.
If this were to never get confirmed, and if I'm able to be sure 100% that it will never get confirmed, then I would send again the payment.
Now, I have never seen a case of bitcoin payment being unconfirmed, so I need to check for the proper way to deal with that, and to be sure it will never get confirmed at some point in the future.
Cheers,
Mux
