Over the years, the common dynamic for hashrate and Bitcoin’s price has been for the former to follow the latter.

The logic behind this is really simple: the higher the price, the more profitable it is to mine and, therefore, more miners connect to the network to seize the opportunity. As soon as difficulty brings profitability back down, growth stops until there’s balance between hashrate and revenue.

However, this dynamic changed abruptly last year. While Bitcoin was crashing to multi-year lows, hashrate skyrocketed to new all-time highs. This event put extreme pressure on miners, who kept seeing their profit margins get thinner and thinner.

As you can see, the relationship between Bitcoin mining hashrate and its price is complex and multifaceted. This article will explore the dynamic between these two factors.

Let’s dive into it.

Starting with the Bitcoin mining basics

Bitcoin mining hashrate is a measure of the computational power being used to secure the Bitcoin network and process its transactions.

The hashrate is expressed in hashes per second and is a critical factor in determining the security and decentralization of the Bitcoin network.

Essentially, miners encrypt the transaction data using the SHA-256 algorithm and obtain a hash — a 64-digit string of hexadecimal characters — in return. They have to do this until the hash they obtain is lower than a certain value, set by the Bitcoin protocol, called difficulty. The amount of hashes a miner can guess per second is what we know as “hashpower” and the total amount of hashpower working on the Bitcoin network is called “hashrate,” although these terms are often used interchangeably.

The more hashrate a miner has, the more chances they have to find a block.

Therefore, it is only logical that, when mining profitability is on the rise, miners strive to increase their hashrate to take advantage of the opportunity. Let’s dive deeper into this.

Does hashrate follow price?

Take a look at the chart below. As you can see, there is some correlation between the price of Bitcoin (red) and hashrate (green). As price increases, hashrate draws a similar pattern, often lagging behind by a couple of weeks.

Similarly, after Bitcoin fell by over 50% in 2021, hashrate quickly followed, only to recover when Bitcoin did as well. Yet, as you can see, 2022 paints a different picture, with hashrate growing non-stop as Bitcoin fell lower and lower.

While this is common to see, there are many other factors involved in this dynamic. Let’s dive into that as well.

The relationship between price, hashrate, and profitability

As we mentioned, Bitcoin hashrate refers to the overall processing power of the Bitcoin network, and is an indicator of the network’s security and stability. The higher the hashrate, the more secure the network and the harder it is for bad actors to manipulate the system.

This is because the Bitcoin protocol automatically adjusts the mining difficulty according to the total hashrate. “Difficulty” determines the parameters that a block’s hash has to follow to be accepted by the protocol. As the hashrate of the network increases, so does the difficulty, making it harder for miners to find accepted hashes.

In reality, difficulty is a security measure in face of hashrate’s growth.

The idea is that if a bad actor wanted to launch a 51% attack on Bitcoin — in other words, taking control of the network by owning more than half the hashrate securing it — the protocol’s difficulty would gradually increase the cost of a potential attack as they added more hashrate to the network.

As a consequence, difficulty adjustments have a direct impact on mining profitability, as the harder it is to find a block, the more electricity and computational resources miners have to spend to earn rewards. In fact, difficulty is the main reason why the average cost of earning 1 BTC from mining increased from virtually $0 to almost $20,000 up to 2022.

However, there are other important factors that affect profitability, such as the cost of mining, including the cost of electricity and equipment, and the price of Bitcoin. This last one is also a critical one. Indeed, miners can relocate or strike deals with providers to find cheaper electricity, but they can’t determine the price of Bitcoin.

As the price of Bitcoin increases, the profitability of mining also increases, making it more attractive for miners to join the network and add to the hashrate.

Implications of the dynamic between multiple factors

There are several secondary implications that derive from Bitcoin’s design and architecture including all these factors.

For example, one of the primary ways in which Bitcoin mining hashrate can affect price is through its impact on the overall security of the network. As more computational power is added to Bitcoin, it becomes more secure and resistant to potential attacks. This increased security makes the network more valuable and attracts more investors, which in turn drives up the price of Bitcoin.

Another way in which Bitcoin mining affects price in the short term is through its impact on the supply and demand of Bitcoin.

If profitability is low, miners may be forced to sell their Bitcoin to cover the costs of mining. And albeit this shouldn’t affect the market in the long-term, it can put intense selling pressure on Bitcoin which may lead to short term drops in price.

Summing up, the relationship between Bitcoin mining hashrate and its price is complex and multifaceted. Hashrate, profitability, and price are deeply intertwined and affect each other in multiple ways.

That is why, if you’re interested in Bitcoin mining, it is fundamental to learn the dynamics of this relationship to understand potential changes and circumstances that affect Bitcoin’s price.
