ive traded over 60m between my main and pure.
im not to worried about gettin ban for that but if your nervous i would just go duel arena and make it like a legit staking match but make sure you win on acc you want money traded to you know?
Idk how this works when it comes to transferring from several accounts to 1 account. But if your swapping between main and pk char, just trade it. I'm sure this doesn't appear as RWT since its the same IP and can be 2 family members trading.
I just trade it to be honest. Jagex can track gold and if they really did want to ban you they would. Staking it or drop trading isn't fooling anyone, neither is transferring between 4 mules.
