Best Bitcoin Mining Hardware (May 2018)

In mid-2018 there are lots of ASICs available for mining Bitcoin, all with various initial costs and power usage/hashpower ratios.

This guide will go through Bitcoin ASICs currently available, estimating how profitable these are based on the latest Bitcoin difficulty & price in May 2018. We posted a separate guide on Bitcoin mining software here.

We have a Crypto Coin Tracker that supports coin wallets, this can be used to track your mining profit in fiat (USD) and generate data needed for tax reporting.

One Year Break Even Comparison

Using our ASIC Bitcoin miner calculator, we can give optimistic and skeptical estimates for profitability. This guide is useful for an initial comparison, and the calculator can be used to get the most up-to-date data. We assume that if mining stops being profitable, you'll turn the miner off - so for the Antminer S9 for example, the yearly income is $0 (but this would actually be negative if you kept it running).

The links to Amazon below are affiliates, so we'll get some money if you buy something using these.

Optimistic yearly income: $0 (US), $0 (UK)
Skeptical yearly income: $0 (US), $0 (UK)

If the miner you want isn't available on Amazon, we wrote a guide suggesting some alternatives here.

Assumptions (this is just if you're interested, not required reading):

  1. Block reward of 12.5 (as this won't change until June 2020).
  2. We assume a monthly difficulty increase of 15% for optimistic predictions, and 40% for skeptical predictions.
  3. We assume Bitcoin's price will increase by 10% monthly for optimistic predictions, and 8% monthly for skeptical predictions.
  4. Electricity costs vary massively worldwide, so we provide estimates for the US (where we assume power is $0.10 per kWH) and the UK (where we assume power is $0.20 per kWH). Countries like China are cheaper, so you'd get a higher return.
  5. The largest mining pool (AntPool) charges 2.5% fees, so we use this fee for calculations.
