2. Cardano (ADA) is a third-generation decentralized app (DApp) and smart contract platform compared to Ethereum, EOS, and Tron. Cardano's design philosophy includes scalability, interoperability, and sustainability. It can handle transaction processing at faster speeds, even with increased users. Different devices can communicate with each other through standard, universal protocols in the future. The project remains safe and can be sustainably developed, and is a decentralized platform that isn't controlled by any company or organization, similar to bitcoin.

3. Nash Exchange (NEX) now plays a vital role in the growing popularity of the Security Token Offerings (STO). Nash is a registered security token that has participated in and led the development of several projects. Nash Exchange is a decentralized exchange that allows NEX token holders to calculate dividend earnings.

4. Basic Attention Token (BAT) mainly solves issues related to delivering advertisements. Google and Facebook collect and exploit users' information and behavior for sales, without their consent. Intermediaries receive the maximum fee percentage, users often block delivered ads using software or commit fraud, which severely affects the efficiency of ad delivery. Brave Browser (which supports the usage of BAT tokens) has seen rapid growth in publishers' usage over the last six to twelve months.

5. Chainlink (LINK) solves the problem of obtaining external data for smart contracts. Oracles for smart contracts can be used to bring external data into the blockchain. Companies such as Google support the development of chainlink, which also has several chainlink partner names.

6. Ethereum (ETH) has maintained its long-term position as the second most popular cryptocurrency in the Top 100 Cryptocurrencies for many years. Its ecosystem has grown exponentially to the point that it can no longer be called an altcoin. While personally, long-term prospects may not be optimistic, it is expected to grow rapidly in the short-term.
