Bittrex is a digital money exchange that specializes in crypto-to-crypto trade using different altcoins, BTC included. The coin value is benchmarked against either cryptos or fiat currencies (USD) for accurate trade planning, as shown below.
Trade functions that you can use to swap currencies around are a limit and conditional tools. These functions help you specify the price you wish to get and limit values on which you have an acceptable loss.
Changelly and itBit both do not have any of these functions and are engaged in direct purchase/swap activities. Thus, we consider margin trading at Bittrex adequate for you to use when dealing with many currencies.
Service is available globally and for most regions, basic verification is required only.
