What is Bitcoin Cloud Mining?

Bitcoin Cloud mining or cloud hashing allows users to purchase hashing power hosted in data centers.

Hashflare.io and Genesis-Mining.com are the two biggest operators of bitcoin mining that have been offering contracts for many years.

Bitcoin cloud mining allows people to earn Bitcoins in the absense of bitcoin mining hardware, bitcoin mining software, electricity, bandwidth or other offline issues.

Bitcoin cloud mining is sometimes called cloud hashing that allows users to buy the output of Bitcoin mining power from Bitcoin mining hardware placed in remote data centers.

Then all Bitcoin mining is done remotely in the cloud. This enables the owners to not deal with any of the hassles usually encountered when mining bitcoins such as electricity, hosting issues, heat, installation or upkeep trouble.

 

What are Bitcoin Cloud Mining Advantages?

No excess heat to deal with
Quiet because of no constantly humming fans

Best Bitcoin Cloud Mining Contracts and Comparisons

Bitcoin cloud mining contracts are usually sold for bitcoins on a per hash basis for a particular period of time and there are several factors that impact Bitcoin cloud mining contract profitability.

For example, Pay per GHash/s would be 0.0012 BTC / GHs for a 24 month contract.

Contracts vary from hourly to multiple years. The major factor that is unknown to both parties is the Bitcoin network difficulty and it drastically determines the profitability of the bitcoin cloud hashing contracts.

Bitcoin network difficulty is a measure of how difficult it is to find a hash below a given target.

The Bitcoin network has a global block difficulty. Valid blocks must have a hash below this target. Bitcoin mining pools also have a pool-specific share difficulty setting a lower limit for shares.

The Bitcoin network difficulty changes roughly every two weeks or 2,016 blocks.
