To truly understand whether an investment is worthwhile, it's essential to comprehend the four primary use cases of blockchain technology: coins, platforms, applications, and asset tokenization.

Coins, the earliest form of blockchain projects, act as a medium of exchange for digital assets. They function as the equivalent of currency in the digital world and allow for secure, private transactions. Popular examples include Bitcoin and Litecoin, as well as privacy-focused assets such as Dash, Monero, and Zcash.

Platforms serve as the infrastructure for building decentralized applications, enabling developers to issue tokens and create smart contracts. Ethereum is a good example of a platform that allows for the creation of custom decentralized applications.

Applications utilize blockchain technology to solve problems in various sectors, such as finance, gaming, social media, and property rights protection. CryptoKitties, a virtual pet breeding game, is an example of an application built on Ethereum.

Asset Tokenization is the process of linking physical assets such as gold and the US dollar to blockchain assets. This process increases asset liquidity and reduces transfer costs while enhancing security. The two most significant examples of this are the US dollar-based token USDT and the gold-backed token DigixDao.

When looking to invest in a blockchain project, understanding its use case and potential value is crucial. By understanding this, investors can make informed decisions that will lead to great returns. Finally, it is essential to be confident in your ability to analyze and justify your investment decisions in the face of external noise.
