0). Introduction
Hello miners, investors and traders. I wanted to write about mining equipments long ago but I could not find a time for doing this efficiently.
Today, I am going to explain "Bitmain" miners which is called generally "Antminer", these products are the best products of Bitcoin or SHA-256 algorithm mining. Also there are another miners for Litecoin, Monero, Dash etc. But we will talk about them later.
1) Getting know Bitmain
Bitmain Technologies Ltd., is a privately owned company headquartered in Beijing, China that designs application-specific integrated circuit (ASIC) chips for bitcoin mining.
2) Which products Bitmain sales?
Actually, Bitmain sales so many ASIC miner for the cyrpto industry. As you can see in below picture, BTC and variants, LTC/DOGE coins, DASH, ZEC and the algorith that is provided by similar with these mentoined coins.

As I told you in the introduction phase, we will continue our article in SHA-256 (Bitcoin) minings and variants (forked copies)
3) Bitmain's Bitcoin Miners
Currently, Bitmain sales 5 types of ASIC miners which are very powerful in minin power. As you can see;
Bitcoin Miner S19 Pro+ Hyd. = 198 TH/s that means 
But its based on current difficulty and other parameters. Meanwhile, when I am writing this article the mining difficulty value is:
29,897,409,688,833 - 29.90 T
Do not forget to electricity consumption (5445W)



You can also check which equipment fits you about price/efficiency and how long your plan. Because you should not forget every 12 days difficulty is changing.
4) Conclusion
Please, when you are checking your calculations from internet crypto calculators, do not forget to include mining difficulty and then you should make
forecasting according to past data. In 2017 I was using cloudmining (hashflare) and every 12 day and further 4 months in a row i made calculation
I predicted my contract is going to die. So I stopped my investment on it. What I am trying to say is here, when difficulty is increasing rapidly your
incomes will be decreased directly. And you can not stop it by yourself. What you need to do is keep calm and making calculations how can it be
profitable for you in terms of conditions.

Thank you for reading.
