PND is on the list.

Here is the RULE:

Coin Voting
Please help us to vote the best coins in your opinion. We are going to list the best coins you selected. To avoid spamming for bots, only registered users with order history (Bter Points (BTR) > 1000) or having enough balances are permitted to vote. You get 1 to 10 free votes per hour based on the amount of BTR you have. You can also spend your BTR on payment votes, which is at least 100 BTR per vote based on the votes of this coin and the votes of all coins. All the BTR payments are collected and donated to Bter.com's Public Interest account to support community development, help people, and promote progressive technologies. We reserve the right to add new coins to the markets outside of the voting list.
You are welcome to recommend new coins to us by submitting a ticket at here with the coin announcement link.

Tips: You gain BTR when you are trading. About 5000 BTR per BTC trading.

2 key points:

Everyone could have some free votings per hour.

No need to buy BTR, but BTR is the gift when we trade, for example, buy or sell 1 btc of doge, we will have 5000 BTR.
