BitBounce is developing an email spam solution based on cryptocurrency. BitBounce's crypto-based email spam solution charges senders a fee to have their emails moved to the recipient's inbox. The network is powered by the CREDO token.

Theta Fuel (TFUEL) is the operational token of the Theta protocol, which aims to be a decentralized video delivery network. It is the second token in the Theta protocol, and will work in conjunction with the Theta Token (THETA) that previously existed on their network. Theta Fuel was created to power on-chain operations, such as payments and interactions with smart contracts. The original THETA token will be used for governance purposes.
