Bitcoin vs Altcoins: Mining Revenue Comparison

What Are Bitcoins & Altcoins?

Before you can formally compare mining returns, you need to understand what each of them is. Although both bitcoin and altcoins are cryptocurrencies, there are distinct differences in their origins, technical structure, and mining methods. You figure out these basic concepts so that you can compare the benefits, risks, and applicability of the two in a more focused manner.

Bitcoin: The Digital Gold That Started With Mining

Bitcoin, born in 2009 and proposed by the pseudonym Satoshi Nakamoto, is the world’s first decentralized cryptocurrency. It uses the SHA-256 algorithm to secure the network through a proof-of-work mechanism. That is, miners need to be rewarded with new blocks by constantly calculating complex hashes. Currently, Bitcoin mining has fully transitioned from the early CPU and GPU era to high-performance ASIC miners.
Bitcoin’s best feature is its total cap of 21 million pieces, which makes it regarded as digital gold. As such, it has the potential to be inflation-resistant and retain its value over time.
However, as the hashrate continues to increase and the difficulty of mining continues to rise, individual miners need to invest in high equipment costs and power costs in order to make a steady income. Bitcoin mining can still be your first choice if you have enough money and are looking for long-term stable returns.

Altcoins: A High-Risk, High-Reward Battleground for Diversified Mining

Altcoins are a collective term for all cryptocurrencies other than Bitcoin, including Ether (ETH), Kaspa (KAS), Alephium, and so on. They usually use different algorithms and consensus mechanisms, with the goal of covering diverse scenarios such as smart contracts, payments, and privacy.

This technological difference makes altcoins have their own advantages and disadvantages in terms of network performance, transaction speed, and degree of decentralization. And it also leads to significantly higher market volatility than Bitcoin.

Altcoins have more choices in mining hardware. Some coins still allow the use of GPUs for mining. This lowers the initial investment threshold, though the computing power changes more frequently, making it difficult to stabilize returns.
There are also some emerging altcoins (such as Alephium) that have started using ASIC miners. This is inevitably a sign of optimizing mining efficiency and strengthening network security.

It is worth noting that the mining difficulty adjustment mechanism of altcoins is relatively flexible, and the influx or loss of hashrate will be reflected in the change in revenue. Therefore, this has higher requirements for miners’ equipment selection and power cost management.

Analysis of the Stability of Bitcoin Returns

Bitcoin mining returns are considered stable for several reasons.

Bitcoin’s block rewards are halved every four years, but this halving is completely open and transparent. So miners can budget and adjust in advance, and this regularity keeps the earnings curve relatively smooth.

Furthermore, when the volume of bitcoin transactions continues to increase, the proportion of transaction fees in the income of miners will gradually increase. It will effectively alleviate the downward pressure on earnings brought about by the halving of block rewards.

Currently, the competition among miners is very fierce, as the bitcoin network-wide hashrate has reached the level of hundreds of exahashes (EH/s). The percentage of block rewards received by individual miners has been significantly diluted, and the benefits have become more dispersed.

Large mining pools occupy the vast majority of hashrate, and they ensure the relative stability of the revenue by stabilizing the block frequency. For individual miners or small mining farms, earnings fluctuate greatly, making it difficult to achieve sustainable profitability.

Moreover, the Bitcoin network adjusts difficulty quite frequently, but the fluctuations in each adjustment are relatively small, which allows miners to better anticipate changes in the mining environment.There will not be a sharp increase in computing power in a short period of time resulting in a sudden drop in earnings.

The Volatility of Altcoin Returns

A large part of the volatility of the returns from altcoin mining comes from their market structure. The gold pool of most altcoin funds is very shallow, with a total market capitalization of only a few hundred million to a few billion dollars. Once there is concentrated buying, the price of the coin can rise by 50% or even double in a short period of time, and miners’ earnings soar. But similarly, when large investors cash out or market sentiment turns cold, the price of the coin collapses very quickly, and it is not uncommon for earnings to be cut within a few days.

Much of the volatility in returns is closely related to the dynamics of the network’s arithmetic. Taking Kaspa and Alephium as an example, the network-wide arithmetic of these coins often fluctuates dramatically. When the price rises, the influx of new miners pushes up the hashrate and network difficulty, and the unit output is subsequently diluted; conversely, when the market weakens and miners exit, the difficulty is adjusted downward, and the revenue recovers in the short term. In this case, if miners lack a dynamic adjustment strategy, it is easy to fall into the mining stage. High electricity and hardware costs compress profit margins.

Many altcoin projects are still in the early stages, lacking a mature ecology and continuous development support. If they lose market attention, the coin price, trading volume, and network activity will all decline simultaneously. Miners may face a situation where their equipment is idle for a long time and their investment cannot be recovered.

Impact of Power Consumption on Profits

Bitcoin mining has an extremely high demand for electricity. A common Bitcoin ASIC mining machine typically has a power of around 3 kilowatts. If a mining farm has 10,000 mining machines, the daily power consumption can reach 720,000 kWh. Assuming an electricity price of $0.05/kWh, a single day’s electricity expense would be over $36,000 USD.

The cost of electricity will compress miners’ profit margins. For example, when the price of bitcoin falls or the difficulty increases, profit margins narrow dramatically, and some miners even lose money. So, some miners will choose areas with lower electricity prices to ensure higher profitability.

In contrast, altcoin miners usually use mining machines with lower power consumption, mostly between 200 and 300 watts. A 300-watt GPU miner, for example, consumes about 7.2 kilowatt-hours of electricity in 24 hours, with relatively manageable electricity costs. Some of the altcoins have large fluctuations in hashrate due to the small size of the network and the small number of miners. Coupled with the rapid response to difficult adjustments, miners can more quickly adjust accordingly to the ups and downs of earnings.

However, the advantage of low electricity costs for altcoin mining is not absolute. If the price of a coin soars, the hashrate increases rapidly, the network difficulty follows, and the output per unit of hashrate decreases, then the proportion of the cost of electricity rises instead.

Hardware Return on Investment

The high purchase cost of bitcoin miners and rapid technology updates result in a long payback period for equipment investments. After a miner purchases a new generation of ASIC miners, it usually takes several months for the initial investment to be covered by mining revenue. During this period, market price fluctuations and the continuous rise in network hashrate have a direct impact on the speed of return. And the maintenance costs and depreciation of the equipment can also lengthen the overall payback cycle.

The hardware options for altcoins are more flexible, and miners can adjust the scale of their investment according to market conditions. GPU miners are relatively inexpensive, so it is easier to upgrade and change hands. However, there is a high degree of uncertainty in the cryptocurrency market. Frequent price and power changes make it difficult to accurately predict hardware return cycles. Sometimes returns pick up quickly, and sometimes they can be extended, creating greater variability for miners.

Impact of Difficulty Fluctuations on Mining Returns

The frequency and manner in which the network’s difficulty is adjusted shape the ability of miners to plan their returns. In the case of Bitcoin, for example, the difficulty is adjusted every 2016 blocks (about two weeks). While the fixed cycle is less risky when arithmetic is stable, it is prone to passive losses for some miners during arithmetic surges.
For example, when the new generation of ASIC miners went online in bulk, the network-wide hashrate increased by 10-20% for a short period of time. After the next round of difficulty increases, older equipment with higher power consumption and lower hashrate may be eliminated, failing to cover power and O&M costs.

The risks of altcoins are more complex. Most altcoins use a high-frequency adjustment mechanism that recalculates the difficulty every block or several blocks. While this allows for a quick response to changes in arithmetic, it also means increased volatility in returns.
When the price rises, a large number of miners swarm in, and the difficulty increases, leading to a decline in revenue from an otherwise profitable device. When prices fall, the withdrawal of hashrate may in turn allow difficulty to retrace its steps and earnings to recover in the short term.
However, such rapid ups and downs are very unfriendly to small and medium-sized miners, and the slightest error in judgment may result in unprofitable continuous consumption of power during periods of high difficulty.

Earnings Realization and Withdrawal Convenience

Bitcoin, as the largest market capitalization and most actively traded digital asset, has extremely mature liquidity and withdrawal channels. All major exchanges around the world support Bitcoin trading. Miners can quickly complete exchanges on multiple platforms, and large-value transactions have less impact on price and low risk of slippage. This liquidity advantage provides a guarantee of capital turnover for mining operations and reduces the difficulty and time cost of cashing in mining proceeds.

In contrast, some mainstream altcoins have a certain trading volume, and most small and medium-sized coins have limited trading activity and weak liquidity. Miners may encounter transaction delays, sharp price fluctuations, or even the inability to sell instantly when cashing out their earnings. During the withdrawal process, certain small coins may also face problems such as exchange restrictions, strict withdrawal audits, or network congestion. This would then increase the uncertainty of the return of funds.
