These are the 10 most profitable Bitcoin ASICs in 2025

During the last two months of 2024, the profitability of Bitcoin (BTC) mining has seen an increase mainly due to the rise in the price of this currency in that period.

This circumstance, reported by NoticiasVE, led to the currently most profitable ASIC (application-specific integrated circuit) for this task allowing an average of $21.18 daily net profits, according to Whattomine.

Thus, this article will go through the current ASIC options that offer the highest income for those users interested in Bitcoin mining.

1- Bitmain Antminer S21

The first four options belong to Bitmain’s ASIC, the Antminer S21, in its XP Hyd 3U, XP Hydro, XP and Hydro versions.

What factors influence the profitability of Bitcoin miners?

Apart from the qualities of each ASIC, such as its computing power and energy consumption that will impact the development of this practice, there are other factors that influence the profits of miners.

The bitcoin quote It is, inevitably, the most direct factor. As the price of BTC rises, revenue in dollar terms for miners also rises, as block rewards (3,125 BTC currently) and transaction fees paid by users become more valuable.

In this sense, the electricity price It is also an almost equally relevant factor.

He halvingan event that halve rewards per block subsidy every 4 years implies another element to evaluate in mining profitability.

Next, two conditions of the Bitcoin network that modify mining profits could be pointed out. These are the difficulty and the hashrate global network.

Difficulty measures how difficult it is to find a new block and automatically adjusts every 2016 blocks (approximately every two weeks) to maintain the average block generation time in 10 minutes.

An increase in difficulty reflects greater competition in the network, which reduces the chances of a miner obtaining the reward. Conversely, a decrease in difficulty can improve profits.

While, the hashrate is the total computing power of the Bitcoin network. A hashrate high indicates a network saferbut it also implies greater competition.

When it rises faster than the price of Bitcoin, the profitability of miners decreases, as rewards are distributed among more participants.
