safest way to convert RM 250k to USDT?

what's the safest and cheapest way to convert RM 250k to USDT? the cheapest way i can think of is binance P2P, it will be slow but you dont lose out on fees (im looking at you Luno). but moving large sums via binance P2P might flag and get my account frozen. what recommendations do you have? Hata OTC ? anyone tried it?
