How to mine myself with ASIC mining hardware?

The real heroes of the Bitcoin are the miners.

There is a lottery every 10 minutes. Everytime people make transactions every 10 minutes it goes into a block.

The block has to be verified by someone. But you dont want via a single party that can be corrupt.

So anyone that get the block first gets the point.

So it has a difficulty rating depending on how many people are mining what equipment they are using.

So the more people that start mining and the better equipment coming out the harder it gets to mine.

So to improve this they created Pool.

When you combine all your equipment and starts mining on a pool there is a higher chance you can get the mining point.

Bitcoin has the reward system of the 25 Bitcoin.

You can also do solo mining and hope to find the magic number and win 25 Bitcoin.

The reason that they need to keep increase the difficulty is that if more people and more faster equipment comes online it would take less than 10 minutes to find the 25 Bitcoin.

And it must be maximum 6 times an hour 25 Bitcoin being released every 10 minutes.

So it is an arms race who has the fastest and biggest equipment.

In beginning you could hash on your computer CPU and get a few kilohash.

Then with quadcore CPUs you could get a 20 Megahash.

And then people jumped on GPUs that gave about 3-500 Megahash.

Then everybody joined on ASIC miners. That are designed only to run bitcoin hashing.

An example Antminer S3 4-500 Gigahash per second. 500x times faster than a GPU.

The newer S7 can do about 5.5 Terahash in 1250 Watts

So an example:

2 Terahash for 1450 W with 10 cents per kilowat then it is 3$ a day in power.

You can use the calculator enter power, bitcoin difficulty.

There are several options such as USB miners, standalone ASIC miners.

Please note due to the versatility there can be a risk about not being profitable when buying equipment and consider the electric bill.

In some countries 1 kWh can cost up to 0.44$ and in other countries can cost 0.07$

Make sure to do your research beforehand.
