Escrow.com is the best and trusted escrow service, I believe.
If your deal was made here in forum, It's better to avail the trusted escrow so that you can guarantee safety of your transaction because they have reputation to be maintain here.
Maybe OP are looking for a potential coin that might have huge value in the future. Most of the coin available in South Kor. are already pump from day 1so it's hard to scoop fresh coin for a cheap price. I'm not really sure about his real intention but that's the most possible unless he really wants to collect shitty coins. I can dropped him all my useless token for free. I will just need minimal ETH to cover transaction fee.
