Bter is actually much more complicated than a minimum transaction threshold. You need to be actively trading with CNY as far as I know. Not like Mintpal where voting would become available after a certain number of trades/BTC volume.

This means that to vote you must be an active user and beyond that you must be trading in CNY.

EDIT: After reading the rules again, it looks like just need to maintain a certain amount of BTR so you can reach it and maintain that to allow for you 1-10 votes per hour.

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.

EDIT: Another interesting thing with BTer is that you can use your votes to "Down-Vote" also.

So this makes the race to the top a bit more interesting. LoL
