Bitcoin Interest is a fork of the Bitcoin protocol that pays coin holders interest. Bitcoin Interest (BCI) allows users to securely earn interest payments without ever moving coins from their wallets. Bitcoin Interest's developers believe that paying interest, weekly or monthly, on inactive crypto-funds can benefit the entire cryptocurrency market by reducing volatility.
Bitcoin Interest (BCI) is the first cryptocurrency protocol to use the ProgPoW consensus algorithm. ProgPoW is a Proof-of-Work algorithm designed to reduce the centralizing tendencies of ASIC mining by making it easier for standard GPU devices to participate in the mining process.

Beetle Coin is a PoS cryptocurrency that places an emphasis on raising awareness and funds for environmental issues. The coin is traded and listed under the BEET symbol.

TransferCoin is a digital currency with a hybrid PoW and PoS consensus mechanism. TransferCoin uses the X11 encryption algorithm and has a relatively fast block time.
