Learn how get Started on finding the right Asic for Mining Crypto Currency based on your budget and how much you expected to earn per day. First you need to know that mining major crypto currencies with your personal computer days are over. You need a dedicated ASIC (short for Application Specific Intergraded Circuit). It just Engineering terms for Dedicated computer design just for mining a particular Crypto currency. ASIC design for one crypto currency cannot be used for mining different crypto currency. Asics are design based on primary Cryptocurrency Algorithm. Ethash is Etheruem. Scrypt for Litecoin and Dogecoin. You can by the way Split mine Litecoin and Dogecoin from the Same machine. Equihash miners primarily for Zcoin. SHA-256 algorithm is primarily designed for Bitcoin and Bitcoin Cash. Blake256R14 machines for Decred mining. Remember higher the profit per day is very costly to get them. Remember by the time you and I general public get hold of those miners from manufactures open sale, mining difficulty will sky rocket and your daily profitability drops. Daily profit is inversely proportional to difficulty. When manufacture like Bitmain releases machines to the public they are know the release lots of 10,000 machines. This will sky rocket the hash rate because all those machines will be turned on to validate the network. Never go by the daily profit calculator show in the website. You daily profit drops significantly by the time you get hold of those brand new machines. That is why if you are new to crypto get hold of used machine. You can turn that on and start mining in very shot time.
Secondly, I recommend using a second hand mining machine that is already in site like Amazon, Ebay or Ali Express. In the US, Ebay is the cheapest. Amazon is lot pricier. In China, Ali Express is their version of Ebay. You always want to pick a seller with large positive reputation. They will not ship broken and banged up items to keep their reputation up. You can find cheapest in Ali Express but it comes from China and you might have to pay US duty when importing to the USA. I have imported brand new Antminers from China and US customs made me pay 50 dollars for a miner worth two thousand dollars. UPS will not release the item until you pay the customs fee. You can by from Ebay seller and get it shipped with a week. Always use highly reputed seller and read item description with all small fonts. Make sure you get a 100% working miner. Getting broken miners with not working hash boards or controllers is not worth it. You have to be over eBay looking for another controller board and still no guarantee it will work. Remember all eBay cryptocurrency miners are mostly sold as it is. No refunds or exchanges accepted. That means when you buy it you are stuck with it. If you buy a machine like Antminer A3 thinking you want to miner Sia coin because most websites claim it is Blake2B algorithm. However, Sia coin did a hard fork and make Antminer A3 obsolete. You need to do detail research before you put in few thousand or even few hundred dollars in a used miner. I have provided link below for site that describe most minable coins for a given ASIC machine. When mining, everything in crypto can change in crypto over night. I recommend sell portion of your crypto into Stable coins like USDT or Tether to cover electricity costs. As you can see even at 800 Watt for Bitmain L3+ at 10 cents a kilowatt hour you will need $2 a day to pay for electricity. You want to sell crypto right away at least to cover your monthly electricity cost. Remember all these ASIC have dedicated fans built into it. You going to need good ventilation and it will be noicy. You will not able to run inside a small house not more than 1 miner. It is very loud. Your significant other will be mad for the constant loud humming sound of the miner. You will need a separate garage if you are planning running multiple of them. If you need to plug in multiple machines to same fuse you need to computer total current with margin so you do not trip the switch or create fire hazard. I recommend 240 V two phase power outlets and Bitmain 240 V power supply units. When you double the Voltage, since power is equal to Voltage time current, you can double the power delivered from existing wiring in the house breakers. If you are not sure consult a licensed electrician for details. You do not want have fire hazard.
Thirdly, You need know how to set it up. You cannot mine any crypto currency alone. You need to join a large enough pool that is mines that that collectively wins race for mining block. They share the mining profit based on hash rate you contributed to the pool each day. I mostly used Bitmains Antpool. Antpool fees are high but I do not have time to fish around to find less fees and reliable pool. I have a video link above that shows you how to setup Antpool for Litecoin and Dogecoin merge mining. At least Bitmain Asics have three pools that you need to enter. First you need to connect with your computer on the same router or hub and look for the Antminer IP address. You can use any IP scanning software. I recommend IP Scan software like Angry IP Scanner. Look up the IP. Enter the IP address on any browser. This is where you are locally tring to acess the Antminer ASIC. Most Antminer username is root and password is root. Enter that and login to the Antminer Configuration screen. Go to the miner setup screen. Copy the Antpool stratum+tmp with :8888 port number for each pool. There are 3 pools you can connect. This is where if one pool fails (top one) miner will automatically connect to next one in the list. You need to enter your cryptocurrency wallet address as the username. Password in Antminers are 123. You will hear different sounds when miner is failing to connect pools. Other when you internet provider is acting out, Antminer ASIC are mostly plug and play. You will get your mining reward daily credited to your account based on mining pools daily threshold limits. Antpool's Litecoin threshold is 0.001 LTC. Remember daily income fluctuates depending on the difficulty and how many blocks you pool finds for every give block time.
