<>Cryptocurrencies have been compared to Ponzi schemes, pyramid schemes and economic bubbles, such as housing market bubbles. Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were "nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it", and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999). The New Yorker has explained the debate based on interviews with blockchain founders in an article about the “argument over whether Bitcoin, Ethereum, and the blockchain are transforming the world”. >
<>Homero Josh Garza, who founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC's complaint stated that Garza, through his companies, had fraudulently sold "investment contracts representing shares in the profits they claimed would be generated" from mining. >
<>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 response, on Friday, September 19, 2008, the U.S. Department of the Treasury announced an optional program to "insure the holdings of any publicly offered eligible money market mutual fund—both retail and institutional—that pays a fee to participate in the program". The insurance guaranteed that if a covered fund had broken the buck, it would have been restored to $1 NAV. The program was similar to the FDIC, in that it insured deposit-like holdings and sought to prevent runs on the bank. The guarantee was backed by assets of the Treasury Department's Exchange Stabilization Fund, up to a maximum of $50 billion. This program only covered assets invested in funds before September 19, 2008, and those who sold equities, for example, during the subsequent market crash and parked their assets in money funds, were at risk. The program immediately stabilized the system and stanched the outflows, but drew criticism from banking organizations, including the Independent Community Bankers of America and American Bankers Association, who expected funds to drain out of bank deposits and into newly insured money funds, as these latter would combine higher yields with insurance. The guarantee program ended on September 18, 2009, with no losses and generated $1.2 billion in revenue from the participation fees.
One of the best ways to learn about forex is to see how prices move in real time and place some trades using fake money by using an account called a paper-trading account (so there is no actual financial risk to you). Several brokerages offer online or mobile phone app-based paper trading accounts that work exactly the same as live trading accounts, but without your own capital at risk.
