A few months ago, the prices of bitcoin were quite high that everybody thought profitability has made a comeback. However, the profitability of mining depends on largely on the type of mining software used for the computation of complex math problems, the cost of electricity in your particular locality and the current price of the virtual currency.
The good thing with bitcoin mining is the availability of different types of hardware to suit every level and budget. Mining can be a profitable hobby or you can opt to be a full scale bitcoin farm owner if the data center is located in a place where electricity and cheap and the internet connection is fast. It is also important to consider several parameters like power consumption, the cost of equipment and hash rate before making a decision to be a farm owner.
Mining crypto currency like bitcoin is difficult and as more units are mined, the levels of difficulty are increased. With increased difficulty, more complex hardware is necessary. When a lot of people come together to mine, the collection is called the mining pool. Each of the users of the mining pool gets a share of the profits based on valid proof of work. Many users prefer smaller mining pools so as to avoid the concentration of hash power.
Cloud mining is another new concept that allows more and more people to mine. Cloud mining is basically a service that allows interested users to pay for hashing power that is hosted in remote data centers and sold in Gigahash/seconds (GH/s). If you will compare cloud mining with private mining pools, you will notice that the former is more beneficial. If you will mine at your place, you will likely get no more than 6 kWt. Cloud mining is hosted in specialized datacenters where everything is safe and secured and equipped will all the machines necessary to earn some bitcoins.
If you are interested in crypto currency, it is suggested to try bitcoin cloud mining where the cost is relatively cheap and allows you to start mining immediately. Many cloud mining plans are advertised online but make sure to choose a reliable and trustworthy provider.
