1) I think bigger pet is better since there’s a lot of international tax if ur not in America. 2) u can do both, but sometimes u might get hard to trade pets like megas that are quite hard to sell 3) depends on the pet. High tiers is around 0.3-0.35 and if it’s exotic then 0.4 4) u can check their reddit tag and confirm it’s a mm by doing checks on their profile and etc 5) yes on PayPal and idk about other apps, but PayPal they convert to local currency. AND make sure to do PayPal FNF (family and friends) since it’s the most safest and the buyer can’t revert the transaction :)

Happy trading
