Bitcoin mining

Contributor(s): Matthew Haughn

Bitcoin mining is the processing of transactions in the digital currency system, in which the records of current Bitcoin transactions, known as a blocks, are added to the record of past transactions, known as the block chain.

A Bitcoin is defined by the digitally signed record of its transactions, starting with its creation. The block is an encrypted hash proof of work, created in a compute-intensive process. Miners use software that accesses their processing capacity to solve transaction-related algorithms . In return, they are awarded a certain number of Bitcoins per block. The block chain prevents attempts to spend a Bitcoin more than once -- otherwise the digital currency could be counterfeited by copy and paste.

Originally, Bitcoin mining was conducted on the CPUs of individual computers, with more cores and greater speed resulting in more profitability. After that, the system became dominated by multi-graphics card systems, then field-programmable gate arrays (FPGAs) and finally application-specific integrated circuits (ASICs), in the attempt to find more hashes with less electrical power usage. 

Due to this constant escalation, it has become hard for prospective new miners to start. This adjustable difficulty is an intentional mechanism created to prevent inflation. To get around that problem, individuals often work in mining pools.

Bitcoin generally started with individuals and small organizations mining. At that time, start-up could be enabled by a single high-end gaming system. Now, however, larger mining organizations might spend tens of thousands on one high-performance, specialized computer.

In the malware world, one of the more prevalent current threats is mining botnet infections, in which user systems mine for Bitcoin without the owners' knowledge and funds are channeled to the botnet master.

When purchasing mining equipment make sure you have done an initial check of the seller, getting some referral and use trusted payment providers such as Paypal if possible.
I have been looking to get into bitcoin mining but finding it too difficult to start. I bumped into an article online on investments and profit through bitcoin mining and other alt coins. The daily,weekly,monthly income got me really, i  couldn't  comprehend the process but after further enlightenment via comment section i realized i can be assisted and this got me directed to crypto expert whom I contacted via his email address CryptobinaryExpert(at)Hotmail DOT com.Breaking financial barriers is one of the sweetest achievement one can achieve and with a profit of One hundred and twenty nine thousand dollars in a couple of weeks should be regarded as a gain though.
Broadcoin is proving to be better than bitcoin. Nowadays bitcoin ain't as profitable, either in its mining or even trading
if you haven't heard about broadcoin, this is it

I have been at my job for 8 years and was sacked in March, the company I used to work with told me they could not afford to pay me anymore due to the pandemic. I was really devastated and went into depression, so one of my best friends called to check up on me on this faithful night and told me not to worry about anything. Then he introduced me to Bitcoin investment. He gave me the contact of [ BITCOINTECHNOLOGIST@GMAIL dot COM ] and I emailed them and started investing with just $1k and after about a week I had made $25k in profits. Investing in bitcoin can seem really complicated, but it is much easier when you work with an expert like this team. You can reach them for  bitcoin trading/ mining /investment or even retrieval of lost/stolen bitcoin and wallets. You can thank me later.
Thank you bitcointechnologist for helping me out , they are the only legit bitcoinexperts i believe in. Thank you
