The bitcoin transaction rate fees are:

Account registration and verification: free!
Bitcoin offer creation fee: free!
Deposit to CryptoCoinPiggy wallet: free!
Withdrawal from/to another CryptoCoinPiggy wallet: free!

The fee for withdrawal to an external wallet is 0.9%. For large transactions please contact us.
Also, keep in mind that bitcoin transactions come with the network fee which is not controlled by CryptoCoinPiggy, nor do we get any profit from it. The network transaction fee is included in the "transaction fee" field in the send payment form.

For short:

Everything is free except withdrawal to external wallets which holds the lowest rate on the market of 0.9%.
