And new cryptocurrency applications take root with impressive frequency — Cryptomaniaks has a great look at the fast-growing world of cryptocurrency sports betting sites as just one example.
Combining the BSADF with the GSADF test allows the r2 value to vary while still using a backward expanding window. r2 starts at the smallest possible window size, and moves one point at a time towards the end of the time series.

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.
The good news for U.S. customers is that Binance.US does offer the same low trading fees that its parent company, Binance, does. The only slight difference is that the US exchange offers 10 VIP levels whereas the international platform only has 9 VIP levels. However, for almost all traders, that won't make a difference.
