Binance has recently attracted regulator attention around the world. While Binance.US is a separate legal entity from the main Binance platform, it is 90% owned by Changpeng Zhao, who started and controls Binance.com, the world’s largest cryptocurrency exchange. The NYT said it was regulatory attention in the U.S. over money laundering and tax issues combined with the common ownership that concerned potential investors. GreatPoint Ventures confirmed to the NYT it considered investing and declined.
Steep rises and unexpected dives in the price of cryptocurrencies are relatively common. As the market stabilises, the volatility has slowly decreased, but irrationality will always be part of the trading game.

Spot trading means you’re not technically “buying” the cryptocurrency, but instead trading your USD for it through either a market or a limit order. A market order means you agree to trade for the currency at the current market price. A limit order lets you put in a designated price at which you want the trade to occur, and when the currency reaches that price, the trade happens automatically. These orders then incur “maker” (for limit orders) or “taker” (for market orders) fees — though on Binance.US, there’s just a standard 0.1% fee.
