   <p>Bitcoin miners perform a function that is analogous to gold mining, but very different. While gold miners deal with rocks, Bitcoin miners deal with data.</p>
-  <p>Bitcoin mining is the mechanism that keeps everyone in the system synchronized together. To mine, computers that take part listen for transactions (ledger transfer announcements) broadcasted through the peer-to-peer network. The miners process and confirm these transactions by including them in a block and adding it to the blockchain.</p>

To mine, computers that take part listen for transactions (ledger transfer announcements) broadcasted through the peer-to-peer network. The miners process and confirm these transactions by including them in a block and adding it to the block chain.</p>
   <p>Bitcoin miners perform this labor because miners that solve a block earn (1) any transaction fees paid by customers for faster transaction processing and (2) newly created coins, issued into existence according to a fixed formula.</p>
-  <p>Bitcoin mining is a very competitive market. Bitcoin miners are neither able to increase their own block reward beyond the rules in the protocol nor process fraudulent transactions that could corrupt the Bitcoin network. Because anyone can become a Bitcoin miner and the Bitcoin network is the largest distributed computer network in the world, it is extremely improbable that a malicious Bitcoin miner could compromise the blockchain. Thus, Bitcoin mining is used to protect the neutrality and the consensus of the network, even if not all Bitcoin miners can be trusted.</p>

     <li><em><b>Low or zero fees</b></em> - Bitcoin payments currently process with either no fees or extremely small fees. Users may include fees with transactions to receive priority processing which results in faster validating and authenticating of transactions by the network. Additionally, merchant processors exist to assist merchants in processing transactions, converting bitcoins to fiat currencies with daily direct deposits to bank accounts and provide these services for much lower fees and less risk than with Paypal or credit card networks.</li>
     <li><em><b>Less fees and risks for merchants</b></em> - Bitcoin transactions are secure, irreversible and do not contain customer’s sensitive or personal information. This protects merchants from losses caused by fraud or fraudulent chargebacks and there is no need for PCI compliance. This allows merchants to easily expand to new markets where either credit cards are not available or fraud rates are unacceptably high. The net results are lower fees, larger markets and less administrative costs.</li>
     <li><em><b>More protection for consumers</b></em> - Bitcoin payments are made without needing personal information tied to the transaction. This offers strong protections against identity theft. Users are in full control of their transactions therefore it is impossible for merchants to force unwanted or unnoticed charges which can happen with either ACH debits, debit cards, Paypal or credit cards.</li>
-    <li><em><b>Transparency</b></em> - <a href="http://blockchain.info">All information</a> concerning the Bitcoin money supply is readily available on the blockchain for anybody to see, verify, measure, and use in real-time.</li>
-    <li><em><b>Distributed</b></em> - The Bitcoin ledger, commonly called the blockchain, is distributed throughout the world and stored by Bitcoin miners. This adds a level of resiliency and redundancy that is unmatched in the payments space and a payment processing network. For example, the Federal Reserve does all their payment processing at 100 Orchard Street, East Rutherford, New Jersey and have back-up systems that can be brought online within 60-90 minutes at the Federal Reserve Banks of Richmond and Dallas. If those three centers were compromised or destroyed then the entire monetary system of the Federal Reserve would be greatly impaired and probably completely nonfunctional.</li>
