Bitfinex is one of the largest cryptocurrency exchanges

Bitfinex is under scrutiny for a lack of transparency along with issues related to Tether but some of the cloak was pulled back today via a Bloomberg report.

They spoke with ING who confirmed that the exchange has accounts there.

"With companies that are active in the crypto market we are very reserved," Harold Reusken, a spokesman for Amsterdam-based ING said in an email to Bloomberg. "Not with companies that are in traditional markets and receive or do payments with cryptocurrencies, but with parties that are in the chain of cryptocurrencies."

It's great news for the exchange and for crypto because it shows a big bank is willing to work with them after Wells Fargo cut them off last year.
