Question on my purchase

[NinjaProxy]

Hi guys! Just bought 225M for later today. My seller who I actually know personally ironically enough said that it is up to me how we transfer the gold. Do you think I should take precautions doing a duel arena exchange or drop trade, or is 225M a small enough amount that we can just trade it face to face and he just hands it off for nothing with no chance of an RWT infraction. Thanks for your advice!
