Big vouch for Carbon! Bought a 400M rsn. Went first without a MM or transfer service. He lent me the account the RSN was on for as long as I needed to transfer the RSN myself. Big props to him.
Vouch for Carbon! He transferred a rsn worth of 1.5b for me. Everything went smooth, dude is a legend, definitely would use him again. Thank you so much brother <3
