Bitmain Antminer S19j (90 TH) is another miner from the Bitmain Manufacturer slated to be released in June 2021. Antminer S19j 90 TH is the model which is bound to give Bitcoin miners a profitable mining experience. After the specs were issued, we couldn’t help but notice the improvement in features. It uses the SHA-256 algorithm and has a maximum hash rate of 90 TH/s. The miner is bound to mine a total of 43 coins. Read this BITMAIN ANTMINER S19j 90 TH Miner Review for more.

A Brief Introduction of Bitmain Antminer s19j 90 TH Features and Specs

Antminer S19j 90 TH is the miner that everyone is talking about. The initial release date was February 2021, but the miner’s release went to June 2021. The miner is ASIC supported and comes with an ASIC Hub (Non-SSH) recommended software.

Market Place and VIABTC under the SHA-256 algorithm are the most profitable coins. According to the manufacturer, the shipping date for this unit is October 2021.

Most Bitcoin miners want to get their hands on this profitable miner. Current market data shows that the miner could have a profit ratio of above 200 percent. There are no design changes with how it looks comparing it with other Bitmain miners.

We did notice that there are no naked wires with the unit, which is a much-needed improvement. It weighs 14500g, and the size is 195x290x400mm.

You can join leading mining pools that are already gearing up for the arrival of this unit. Get to buy it straight from the manufacturer or a few online stores.

Algorythm of Antminer S19j 90 TH

SHA-256 is the algorithm that you will find under this Bitcoin miner. The algorithm is known for its safety and speed of mining fresh bitcoin. One advantage this hashing algorithm holds over others is a guarantee of safety.

There’s no known vulnerability with this algorithm which makes it amongst the best. Mining with this algorithm will ensure miners get the protection they need from the 51 percent attack.

Efficiency of the S19 j 90 TH Antminer

There’s no exact number for the efficiency of the miner. We will have to run with 90T/3250W as the available efficiency. What this means is that the miner is not leaving any chances when it comes to power. It has a power consumption of 3250W, which is one of the biggest in the industry.

With this power, users should expect to mine faster even though at a price. The electricity cost will be higher than most Bitcoin miners.

Hash Rate of the Bitmain Antminer S19 j 90 TH

It comes with a high hash rate of 90 TH, which is impressive for all reasons. With a high hash rate, miners get the chance to mine faster and in a secure environment. The high hash rate also enables miners to mine Bitcoin better.

Such a miner is effective in enabling miners to grasp new Bitcoin before anyone else. By joining a mining pool, the high hash rate will come at a huge advantage.

Humidity and Temperature settings

A good miner is only efficient if it operates under the manufacturer’s recommended settings. Humidity and temperature play a vital role in providing longevity for the miner. A miner’s lifespan is heavily dependent on avoiding overheating.

Humidity should be at 5 percent minimum and 95 percent maximum. The temperature should be 5 degrees Celsius minimum and 40 degrees Celsius maximum.

Noise and sound emissions

It comes with 75 decibels of sound, which is enough to start a home mining experience. The sound emission is also on the side of large-scale mining, even on a large-scale basis.

The Profitability of Bitmain Antminer S19j 90 TH

The miner will likely be profitable for over a year. With Bitcoin prices skyrocketing, the miner is bound to be highly profitable.

Warranty of the S19 j 90 TH

The manufacturer offers a 180-day warranty from the date of shipping.

Frequently asked questions (FAQ)


How do these machines generate money?

A mining device uses powerful processors to solve the complex puzzles used to secure and validate transactions on a blockchain. By providing some of the global hash power needed, you receive rewards and get paid in crypto-currency. Then you can choose to keep coins or exchange it for other coins or currency.

Can anyone start mining crypto-currencies?

Yes, mining is becoming easier to setup and understand. But you should consider mining as a high-risk investment, the return on investment is not guaranteed, and the benefits are highly variable due to the volatility of the cryptocurrency market.

What are the disadvantages of mining?

Most machines consume a lot of electrical energy, produce a significant amount of heat and generate a lot of noise.

You must choose your machines according to your ability to tolerate these three factors.

Safe place for your gain?

When you mine your gain will be stored in a wallet.

We recommend that you use a hardware wallet, to be the full owner of your coins.
Do not keep all your earnings in an online wallet (exchange, pool…).

The best known and most trusted hardware wallets are:
Trezor and Ledger.

Cryptocurrency exchange platform?

To convert specific coins into Bitcoin or any other cryptocurrencies you will have to go through an exchange service. There are many, here the most famous: BinanceHitBTCCEXKrakenBittrex.

Why is RAM essential for Ethereum mining?

In order to mine Ethereum and Ethereum Classic, your device must load a DAG (Directed Acyclic Graph) file into memory (RAM). This file grows over time, and when this file is larger than your available memory, you can no longer mine.

For example, here is a projection of the size of the DAG file for Ethereum:

– Over 4Gb on December 2020
– Over 6Gb on March 2024
– Over 8Gb on May 2027


How to understand profitability?

The real-time earnings show you the benefits you can expect from a device if you already owned and operated the miner.

This view allows you to see key information at a glance.

Can I change some local parameters in calculation?

Yes, in the ‘Local preferences’ section of the footer, you can:

  • Change default currency (USD, EUR, GBP, more to come…)
  • Electricity cost (price of KWh)

Why do profits change when I refresh the page?

Profits are calculated in real-time according to device specifications and external variables:

  • Network difficulty
  • Block reward
  • Coin value
  • Exchange rate

Displayed values are here to provide actual earnings information for each device for comparison purpose.

How is calculated ROI?

Return on investment (ROI) is the number of days between the purchase and the day you have generated enough income to equal the cost of the miner.

  • ROI = Time to release date + Delivery time + Number of days to break-even.
