Redeem BTCC Mint
We currently only support the import of bitcoins that utilize the mini private key format, as used by BTCC Mint.
To import the bitcoin private key, please follow these steps:
1. Peel off the hologram sticker on your BTCC Mint collectible.
2. The private key will be printed on a small piece of paper on the back of the sticker.
3. Enter the private key into the box below, without any spaces. Please remember that this string is case sensitive. (Do not disclose or reveal the private key to anyone else until you have successfully imported the bitcoins.)
.
Normally you enter the private key in your wallet but it seems that you send the coin's face value, through their website, to your address of choice.
