A US based crypto-exchange that currently handles $150 million in trading volumes has begun offering USD deposits and withdrawals as well as trading pairs. Bittrex says:
“Bittrex now supports eligible personal and corporate accounts for US Dollar (USD) trading, USD deposits, and USD withdrawals.
International customers and those operating in California, New York, Montana, and Washington State with identity verified accounts are eligible.”
Entrance into their fiat trading process seems to be somewhat convoluted with individuals needing to request permission to USD trade after sending ID and proof of address.
It is also limited to just four states in US, but this is the only exchange we’re aware of that has gone from crypto-to-crypto trading now crypto-to fiat in addition.
They used to be the biggest crypto exchange once, overtaking Poloniex, but then Binance came and left both in the dust.
Binance, however, does not yet have fiat trading pairs for USD, but they’re very much trying to offer dollar trading too.
