You don‘t need to understand the details about SHA 256. It‘s only important you know that it can be the basis of a cryptologic puzzle the miners compete to solve. After finding a solution, a miner can build a block and add it to the blockchain. As an incentive, he has the right to add a so-called coinbase transaction that gives him a specific number of Bitcoins. This is the only way to create valid Bitcoins.
<>A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets. Cryptocurrencies use decentralized control as opposed to centralized digital currency and central banking systems. >
<>Two members of the Silk Road Task Force—a multi-agency federal task force that carried out the U.S. investigation of Silk Road—seized bitcoins for their own use in the course of the investigation. DEA agent Carl Mark Force IV, who attempted to extort Silk Road founder Ross Ulbricht ("Dread Pirate Roberts"), pleaded guilty to money laundering, obstruction of justice, and extortion under color of official right, and was sentenced to 6.5 years in federal prison. U.S. Secret Service agent Shaun Bridges pleaded guilty to crimes relating to his diversion of $800,000 worth of bitcoins to his personal account during the investigation, and also separately pleaded guilty to money laundering in connection with another cryptocurrency theft; he was sentenced to nearly eight years in federal prison. >

<>Bitcoin is pseudonymous rather than anonymous in that the cryptocurrency within a wallet is not tied to people, but rather to one or more specific keys (or "addresses"). Thereby, bitcoin owners are not identifiable, but all transactions are publicly available in the blockchain. Still, cryptocurrency exchanges are often required by law to collect the personal information of their users.

<>Hedge funds – Somewhere around 70 to 90% of all foreign exchange transactions are speculative in nature. This means, the person or institutions that bought or sold the currency has no plan of actually taking delivery of the currency; instead, the transaction was executed with sole intention of speculating on the price movement of that particular currency. Retail speculators (you and I) are small cheese compared to the big hedge funds that control and speculate with billions of dollars of equity each day in the currency markets. >

<>In the Forex market, currencies always trade in pairs. When you exchange US dollars for euros, there are two currencies involved. For every foreign exchange transaction, you must exchange one currency for another. This is why the forex market uses currency pairs, so you can see the cost of one currency relative to another. The EUR/USD price, for example, lets you know how many US dollars (USD) it takes to buy one euro (EUR). >
Cryptocurrencies hold the promise of making it easier to transfer funds directly between two parties in a transaction, without the need for a trusted third party such as a bank or credit card company; these transfers are facilitated through the use of public keys and private keys for security purposes. In modern cryptocurrency systems, a user's "wallet," or account address, has the public key, and the private key is used to sign transactions. Fund transfers are done with minimal processing fees, allowing users to avoid the steep fees charged by most banks and financial institutions for wire transfers.
In addition, the SEC is adopting amendments designed to make money market funds more resilient by increasing the diversification of their portfolios, enhancing their stress testing, and improving transparency by requiring money market funds to report additional information to the SEC and to investors. Additionally, stress testing will be required and a key focus will be placed on the funds ability to maintain weekly liquid assets of at least 10%. Finally, the amendments require investment advisers to certain large unregistered liquidity funds, which can have many of the same economic features as money market funds, to provide additional information about those funds to the SEC.
It should be noted that there is no central marketplace for the Forex market; trading is instead said to be conducted ‘over the counter’; it’s not like stocks where there is a central marketplace with all orders processed like the NYSE. Forex is a product quoted by all the major banks, and not all banks will have the exact same price. Now, the broker platforms take all theses feeds from the different banks and the quotes we see from our broker are an approximate average of them. It’s the broker who is effectively transacting the trade and taking the other side of it…they ‘make the market’ for you. When you buy a currency pair…your broker is selling it to you, not ‘another trader’.
