What is an ASIC Bitcoin Miner?
Since it’s now impossible to profitably mine Bitcoin with your
computer, you’ll need specialized hardware called ASICs.
Here’s what an ASIC miner looks like up close:
Originally, Bitcoin’s creator intended for Bitcoin to be mined on
CPUs (your laptop or desktop computer). However, Bitcoin miners
discovered they could get more hashing power from graphic cards.
Graphic cards were then surpassed by ASICs.
Think of a Bitcoin ASIC as specialized Bitcoin mining computers,
Bitcoin mining machines, or “bitcoin generators”.
Nowadays all serious Bitcoin mining is performed on dedicated
Bitcoin mining hardware ASICs, usually in thermally-regulated
data-centers with low-cost electricity.
Most Efficient Bitcoin Miners
Good Bitcoin mining hardware needs to have a high hash rate. But,
efficiency is just as important.
An efficient Bitcoin miner means that you pay less in electricity
costs per hash.
To improve your efficiency, there are also companies that will let
you order hardware to their warehouse and run the miners for you.
You could also cloud mine bitcoins, though these deals are usually scams. Both options are also a lot
less fun than running your hardware!
Precautions for startup
1. Check all connecting wires to make sure they are connected
correctly. Make sure they are firmly connected and in the correct
alignment position.
2. When powering up the machine, be sure to power up the operation
board first and then the control board.
3. The total current of S9 is about 8 A at 220 V and 9 A at 110 v.
Most household power outlets provide only 10 amps. For your safety,
if you operate S9 at home, power it through two sockets located on
a separate power line. If you are not familiar with residential
electricity wiring, we recommend that you do not use this machine
for home mining.
4. When setting up the equipment, please leave proper space between
the power supply and the miner.
5. S9 uses DHCP protocol to obtain IP address. The default login
user name and password are "root"
FAQ
1. How can I trust you?
A: We can do Escrow for you as long as you willing to pay the
transaction fee.
2. If my miners dont work, what can I do?
A: All miners will be tested before shipping out. We will teamview
and help you to solve the problem for programing issues. For large
quantity, we will provide back up accesorries, like control board,
hashboard for you to replace right away. More discounts can be
negotiated.
3. Is mining still profitable?
A: Hard to say.
4. What models is the best?
A: It depends. Your electricity cost, your budget, and how you know
the market etc are elements for you to consider.
