Recently, there has been an increasing discussion about what cryptocurrency burns are. Especially since the London hard fork, after the Ethereum burn mechanism gained attention, this concept has become more familiar.

Simply put, a cryptocurrency burn is the process of sending tokens to an inaccessible wallet address (called a burn address or dead address) to permanently remove them from circulation. Once tokens are sent there, they never return. In theory, anyone can burn coins, but practically it means discarding your own money, so normally the development team executes it strategically.

Why do they do this? When the supply decreases, scarcity increases. Considering the supply and demand relationship, a reduced supply can lead to a potential price increase. Between 2017 and 2018, many projects like BNB, Bitcoin Cash, and Stellar experimented with this.

However, caution is necessary here. Burning cryptocurrency does not necessarily increase its value. In fact, it can be used fraudulently. For example, developers might claim they burned tokens while actually sending them to their own wallets, or use it to hide large holdings. In short, making investment decisions based solely on burns is risky.

On the other hand, there is another approach called buybacks. This involves companies purchasing tokens from the market and holding them in the development team's wallet. Unlike burns, the bought-back tokens are not completely destroyed. Some major exchanges, for instance, conduct buybacks using 20% of their quarterly profits. There are records of 1,335,888 tokens being removed from the market in October 2021.

The main difference between buybacks and burns is that buybacks are automated and guaranteed by smart contracts. Unlike traditional stock buybacks, they are executed exactly as programmed.

Regarding the burn mechanism, there is a consensus mechanism called Proof of Burn (PoB). Miners burn coins to earn the right to generate blocks. It is more energy-efficient than Proof of Work, but it can lead to centralization as large miners have an advantage.

Ultimately, the goal of both cryptocurrency burns and buybacks is the same: to reduce supply and increase token value. However, their methods and effects differ. Burns completely remove tokens from supply, while buybacks limit circulation but retain tokens as project assets.

The benefits include potential long-term price stability and improved liquidity. Investors are also encouraged to hold. However, there are drawbacks. Deflationary currencies can suppress consumption, and if the burn rate exceeds the growth rate, it might hinder asset appreciation.

In practice, projects like major exchanges and Nexo conduct buybacks to adjust market prices and maintain investor trust. Since similar techniques have been used in traditional financial markets, the same logic applies to cryptocurrencies.

In conclusion, both cryptocurrency burns and buybacks are important tools in tokenomics design. However, investment decisions should not be based solely on these mechanisms; it’s essential to understand the overall project fundamentals and the intentions of the development team. It’s important not to be swayed only by superficial numbers.
