Welcome and enjoy your stay
My advice as someone who has previously sold ZCoins would be to spend some on yourself.
Basic staple of "good items" would be Jack Head, walker bot, Meto Wing, Dark Meto Gun and P EF or S EF
Right now the prices are discounted for zylon coin items compared to what they used to be so to accept one
Of those items (which can be bought for zc) in exchange for zc would most likely be at your loss.
Anyway also like cooky said, with a post count of only 2, it will probably require you to go first in a trade, but don't hesitate to ask one of us staff members to middle man your trade to avoid scams (:
