Halving and Emissions: How Coin Supply Schedules Affect Mining ROI

Bitcoin Mining Profitability Halving: A Real Example

What Happened in 2025

Let’s examine the actual changes of the April 2025 Bitcoin halving event.

Before halving, miners were rewarded with 6.25 Bitcoins for every block they successfully mined. Suppose Bitcoin were valued at $40 000; then miners would have gotten $250 000 for a block.

After halving, the reward dropped to 3.125 Bitcoins, which equals $125 000 per block. So miners’ income per block suddenly decreased by $125 000.

However, the thing that caught our attention next was that the Bitcoin price didn’t fall, but it actually increased in the months that followed. This was a blessing to the miners as they could make more money even though their bitcoin rewards were halved. This is similar to being paid fewer slices of pizza each time, but each slice has become more valuable, so you are not that hungry anymore.

Here’s what we learned from 2025:

• Having the newest, fastest mining computers matters a lot
• Getting money from transaction fees became more important
• Big mining companies had an easier time surviving
• Location matters mining in places with cheap electricity wins

Mining difficulty adjustment halving impact also helped.When mine miners closed down, those who remained found it easier to continue mining. We’ll clarify this further in the following section. The main takeaway? Halving is hard, but miners who get ready beforehand can not only survive but also make a profit.

Halving Coin Supply Schedule: Different Coins, Different Rules

Bitcoin, Litecoin, and Dogecoin Compared

Not every cryptocurrency uses halving the same way. Bitcoin mining cuts rewards in half every four years, but litecoin mining also halves rewards every four years with different timing. Litecoin has 84 million total coins compared to Bitcoin’s 21 million, so it has more coins but follows the same halving idea.

Now here’s something cool about Dogecoin it doesn’t halve at all! Dogecoin keeps giving miners the same reward forever: 10,000 DOGE per block. This means Dogecoin keeps creating new coins constantly. Some people ask about dogecoin mining earnings halving effect, but that’s a trick question because Dogecoin never halves.

Here’s a simple comparison:

• Bitcoin: Cuts rewards in half every 4 years
• Litecoin: Cuts rewards in half every 4 years (different schedule)
• Dogecoin: Never cuts rewards, stays the same forever
• Ethereum Classic: Reduces rewards by 20% every few years

Knowing these differences, miners can identify which cryptocurrency is the most profitable for them to mine. Some miners mine several cryptocurrencies at the same time to diversify their risks. Even if one coin’s rewards become lower, they can still earn from other coins. Think about it as having several jobs, so you are not totally dependent on only one source of income.

Mining Difficulty After Halving: Why Mining Gets Easier

The Network Fixes Itself

Here’s something that helps miners survive halving: mining difficulty automatically adjusts. Think of it like a video game that gets easier when you’re losing and harder when you’re winning. When halving happens and miners start losing money, some people turn off their mining computers. With fewer computers competing, the cryptocurrency network automatically makes mining easier.

This happens in a cycle:

• Halving cuts rewards in half
• Some miners can’t afford to continue and quit
• Fewer miners means less competition
• The system makes mining easier for everyone left
• Remaining miners can earn more

For Bitcoin, this recalibration takes place by itself every two weeks. After the 2024 halving, the difficulty was reduced by around 8% as mining operations that were not making money closed down.

That was a great relief for the rest of the miners as they could keep on making profits even with the reduced rewards. It’s Mother Nature’s method of equalizing the situation.

Just visualize this situation as a pie, eating race. If there are a hundred contenders and only ten pies, then it’s almost impossible to satisfy everyone. But if 50 people quit because they’re full, now 50 people are sharing those 10 pies and suddenly everyone gets more. Mining pools benefit from this too because there’s less competition overall.

Transaction Fees Mining Revenue: The Extra Money

Getting Paid Beyond Block Rewards

Here’s a fact most beginners are not aware of: miners don’t only get block rewards. They also get mining rewards from transaction fees. The thing is, every Bitcoin transaction is associated with a small fee and miners get these fees as additional rewards to the block rewards. At the moment, transaction fees make up 2- 10% of miners’ total earnings, but this figure keeps going up.

So, after a halving, why do transaction fees become more significant?

Simply, if block rewards decrease, transaction fees have to make up a larger share of miners’ income. To give you an idea, a restaurant earns its money firstly from meals (block rewards) and also from tips (transaction fees). If the prices of meals fall, tips become more critical for the survival of the restaurant.

Here’s how it works:

• Someone sends Bitcoin and pays a $5 fee
• Miners compete to process that transaction
• The winning miner gets the fee plus block reward
• During busy times, fees can be $20, $50, or even higher
• More transactions mean more fee income

Smart miners focus on the network traffic to determine the busiest time because consequently, fees soar. There are instances when a miner’s income from transaction fees can be more than doubled. Experts believe that eventually, transaction fees will cover around 30-50% of mining costs. This change turns mining from simply generating new coins to handling people’s payments.

ASIC Miner ROI Calculation After Halving: Easy Examples

Can You Still Make Money?

Let’s do some simple math to see if ASIC Miner ROI calculation after halving still makes sense. Imagine you buy a mining computer for $5,000. It uses $7 worth of electricity every day. Before halving, you earn $26 worth of Bitcoin daily. Your profit is $19 per day ($26 minus $7). At this rate, you’d earn back your $5,000 in about 263 days (about 9 months).

Now halving happens. Your daily Bitcoin earnings drop to $13 (half of $26). Your electricity still costs $7. Now your profit is only $6 per day. To earn back your $5,000 investment now takes 833 days (about 27 months)! That’s three times longer.

Before Halving:

• Daily earnings: $26
• Daily electricity: $7
• Daily profit: $19
• Months to break even: 9 months

After Halving:

• Daily earnings: $13
• Daily electricity: $7
• Daily profit: $6
• Months to break even: 27 months

This shows why timing matters. Many experienced miners buy equipment right after halving when prices drop because everyone panics. Then they have four years to mine before the next halving. The key lesson? Do your math before buying mining equipment. Make sure you can still profit after the next halving hits.

Coin Emission Schedule Explained: The Big Picture

Planning for the Future

Let’s talk about the long-term plan for cryptocurrency creation. Bitcoin has a maximum limit of 21 million coins, that’s all that will ever exist. Right now, about 19.6 million have been mined. Only 1.4 million are left, and they’ll be mined slowly over the next 116 years. The last tiny piece of Bitcoin won’t be mined until around the year 2140.

Here’s Bitcoin’s future schedule:

• 2028: Rewards drop to 1.5625 BTC
• 2032: Rewards drop to 0.78125 BTC
• 2036: Rewards drop to 0.390625 BTC
• 2140: Final Bitcoin gets mined

Each time the bitcoin halving happens, it’s less significant in terms of dollars, but the reward is still halved. It’s the same idea of repeatedly cutting a pizza in half. The first cut is a big deal, but by the tenth cut, the pieces are practically crumbs. Understanding this schedule allows mining farms to plan for years. They have complete knowledge of the dates when reward halves will occur and can thus prepare their budgets accordingly.

Other cryptocurrencies are on different schedules. Litecoin will end its mining operations sometime in 2142. Ethereum Classic will last until 2070. Dogecoin keeps producing new coins forever. Savvy miners examine these schedules and pick the coins that are logically worth mining for the long term based on when and how much the rewards are reduced.

Ethereum Classic Halving 2026: What’s Coming Next

Getting Ready for the Next Big Change

Ethereum classic halving 2026 is coming soon, and it actually works differently than Bitcoin. Rather than cutting the rewards in half like Bitcoin, Ethereum Classic decreases the rewards by 20% every 2.5 years or so. The next cut is expected to be around March 2025 and will reduce the rewards from 2.56 ETC to approximately 2.048 ETC per block.

This milder method means miners will not be as shocked. A 20% cut is definitely easier to deal with than a 50% cut. It’s like your pocket money going from $10 to $8 instead of $10 to $5. You still notice it but it’s not so painful. However, after several 20% cuts, the overall effect will be big.

Here’s how to prepare:

• Watch Ethereum Classic’s price compared to mining costs
• Check if your mining equipment still makes sense to run
• Consider mining different coins if needed
• Plan equipment upgrades for maximum profit before reduction

Ethereum Classic will keep reducing rewards until around 2070, with a maximum supply of about 210 million ETC. Unlike Bitcoin’s dramatic halvings, ETC’s gradual reductions give miners more time to adjust their operations. This makes planning easier, but you still need to stay alert and adapt to each reduction. Many miners prefer this smoother approach over Bitcoin’s sudden cuts.
