Yes, I made a small PPC deposit to try the exchange out for the first time. I didn't see anything posted anywhere about a minimum withdrawal limit.
I have 185 more PPC in bitparking right now and a few hundred more in my wallet. I want to know that the site works before I go placing all of my coins there.
Fair enough, I guess. But most sites have a mininum of 0.1 BTC or even 1 BTC to withdraw, to my knowledge.
