Mistakes like this happen throughout finance when, for instance, traders mess up details of their intended trades, entering the wrong price or order size. An erroneously large trade, as one example, can overwhelm an exchange's order book, leading to a quick and massive decline. The entire U.S. stock market famously flash crashed back in May 2010, though equities have mostly avoided trouble since that era.
Security is a major concern when investing in cryptocurrencies. This is because there is no way to get back tokens once they have been transferred out, making the need for a secure platform all the more important. 4JNET was built with this concern in mind.

Virtual currencies. Like fiat currency, virtual currencies such as Bitcoin, Litecoin, and Ether are intended as a medium of exchange that enables two parties to transact business. But there are important differences: No physical coins or bills. Virtual currencies exist only in computer code. Except for visual representation of Bitcoin and altcoins in advertising and displays, and coin-like tokens that may be produced for marketing purposes, there are no actual coins or bills. Not legal tender. Virtual currencies are not legal tender and are not issued or backed by a government. However, many virtual currencies, which are called convertible virtual currencies, can be redeemed for fiat currency on a number of exchanges. No regulation. Virtual currencies are not regulated by any government agency or authority. However, regulation is being considered, especially where virtual currencies function as securities when they’re used to raise capital and when traded on exchanges.
