What you need to do:
1. Go to the website.
2. Choose AsiaCoin and click Submit.
3. Fill out the form to get your own BTC deposit address.
4. Send 0.001 BTC - or equivalent in LTC/Doge - to that address (make sure to add a transaction fee to ensure it arrives within 4 hours!)
5. Confirm your email (click on the link sent to your email). They will send the confirmation email after your BTC transaction gets 6 confirmations. If you don't do this, your vote won't get confirmed.
Done! Please read my other post about CoinPayments to know why this is very important for AsiaCoin.
Don't forget to click on the link in the confirmation email, which they send once your transaction is completed and after its 6 or 10 confirmations. If you don't do this, your vote won't count.
