What Is a Hard Fork?
A hard fork occurs when a blockchain splits into two distinct networks. It happens as a result of modifications to the blockchain’s code that render the previous version incompatible. Developers, network users, or the community may suggest modifications to improve functionality, security, or speed. The network can break up if the community is not entirely in agreement.
The fork allows both cryptocurrencies to share the same blockchain history up until the block where the fork occurred; thereafter, each independent blockchain continues on its own.
Reasons for Hard Forks:
- Fix security vulnerabilities.
- Improve transaction speed or efficiency.
- Add new features to the network.
- Resolve disagreements within the community.
One famous example is Bitcoin Cash. It split from Bitcoin in 2017 because some developers wanted larger block sizes for faster transactions. Another well-known hard fork is Ethereum Classic, which split from Ethereum after a major hack in 2016.
What Is an Airdrop?
Airdrop means free distribution of new cryptocurrency into the wallets of users. Developers do this to promote their project and gain new users. Airdrops can happen for many reasons, such as marketing campaigns or rewarding loyal users.
Unlike hard forks, airdrops do not require a blockchain split. Instead, developers send new tokens to existing wallet holders. Sometimes, users must complete tasks like signing up for a newsletter or following a social media account to receive the tokens.
Reasons for Airdrops:
- Promote a new project.
- Reward loyal users.
- Increase awareness and adoption.
- Encourage trading and market activity.
Some well-known airdrops that gained value include UniSwap (UNI), dYdX, Arbitrum (ARB), and ApeCoin (APE). However, many airdrops end up worthless because they fail to gain interest or utility.

Are Airdrops Worth It?
Many airdrops end up worthless. When people get free tokens, they often sell them immediately, causing prices to drop. However, some airdrops become valuable if the project succeeds. If an airdrop token gains utility and demand, it may increase in value over time.
Can You Make Money from Airdrops?
It is possible, but not guaranteed. Some airdrops, like UniSwap’s UNI token, gained significant value. Others became worthless because they failed to attract enough users or investors. Researching projects before participating in an airdrop is essential.
Are Hard Forks Good or Bad?
Hard forks can be both positive and negative. Changes might strengthen a blockchain if the improvements are observed and supported by the community, while on other occasions, a fork can just lead to more confusion and fragmented user bases. Success in this respect is about adoption and, ultimately, market demand.
Hard forks and airdrops both introduce new cryptocurrencies but in different ways. Hard forks result from blockchain changes, while airdrops are marketing tools to distribute new tokens. Understanding these concepts can help crypto investors make better decisions.
Investing always requires research, be it new coins coming from a hard fork or an airdrop, since not all projects end in success but just disappear in a puff of smoke. Know the risks.
