Eco-friendly mining without the use of sophisticated equipment. You simply store coins in a special wallet, keeping the blockchain running, and get rewarded for it.

You can take the coins away at any time. Each BTCa coin is equal to a bitcoin (BTC), one to one.

You will need:

– At least one Bitcoin Additional coin

Rewards for stackers: 1% (0.005 BTCa) is awarded every minute and distributed to all stackers. The distribution depends on the age and number of coins sent to the stacker. The more coins, the more likely you are to receive rewards.

No risk to your own funds. Your coin balance will be multiplied by ten times for a higher Bitcoin Additional eco-mining reward.
