What Are Bitcoin and Ethereum?
Bitcoin was the first cryptocurrency, created in 2009. It’s a decentralized digital currency that allows peer-to-peer transfers without banks. Think of it as digital gold—limited supply, scarce, and stored on a blockchain.
Ethereum came later, in 2015. It’s more than just a currency; it’s a platform for smart contracts—self-executing agreements that run on its blockchain. Ether (ETH) is the native token used to power these contracts.

Both are built on blockchain technology, a distributed ledger that records every transaction across thousands of computers worldwide. This ledger is transparent, tamper-resistant, and decentralized.
How Do Bitcoin and Ethereum Work?
When you buy Bitcoin or Ethereum, you’re acquiring digital assets stored in a digital wallet. Transactions are recorded on their respective blockchains.
For example, if you send 0.1 BTC to a friend, your transaction is broadcast to the Bitcoin network. Miners verify it, include it in a block, and add it to the chain.
Ethereum works similarly, but with additional features. You can create or interact with smart contracts—programs that automatically execute when conditions are met. For instance, you might escrow funds until a service is delivered.
Both assets are stored as entries in the blockchain, accessible via public addresses. You control these assets with private keys, which are like digital signatures.
Why Does This Matter for Your Taxes?
The IRS treats cryptocurrencies like property. That means each transaction—buy, sell, or exchange—is potentially taxable.
**Example:**
- You buy 1 Bitcoin at $10,000.
- Later, it’s worth $20,000.
- If you sell or trade it at that point, you realize a $10,000 capital gain.
**Asset Types:**
- Bitcoin and Ethereum are considered property, not currency. So, exchanging one for the other, or using them to buy goods, can trigger taxable events.
**Why It Matters:**
- Many users don’t track these transactions properly.
- Failing to report gains or misclassifying transactions can lead to penalties.
- The IRS has issued guidance but hasn’t provided detailed rules for every scenario, leaving gaps in how some activities are taxed.
**Common Confusion:**
- Is holding crypto taxable? No, just when you sell or exchange.
- Are airdrops or staking rewards taxable? Usually, yes, when received.
- Does moving crypto across wallets or chains trigger taxes? Not if you’re not disposing of the asset, but the IRS hasn’t issued clear rules on chain-hopping.
Current IRS Guidance and the Gaps
The IRS has issued Notice 2014-21, which clarifies that cryptocurrencies are property, not currency. This means every sale or exchange can generate a taxable event.
However, specific scenarios—like hard forks, airdrops, staking, or wrapped tokens—are less clearly defined. Many tax professionals interpret these based on existing property rules, but consensus is lacking.
For example, if you receive 1 ETH as staking reward, many consider that as ordinary income at the fair market value at receipt. If you later sell it, you have a capital gain or loss based on that basis.
Because guidance is incomplete, taxpayers risk misreporting or missing taxable events. Consulting a tax pro familiar with crypto is advisable, especially for complex activities.
