Earlier this week an email was sent to Reuters by ING Bank, which continues its banking and financial services activities in the Dutch finance group and many countries. The email from ING Bank confirmed that Bitfinex, one of the world's largest Bitcoin stock exchanges, has a bank account in the Netherlands according to daily trading volume.

ING spokesman Harold Reusken confirmed that Bitfinex had a bank account with ING in the Netherlands. Reuters said last year that he had not been clear about how Bitfinex managed banking since the split with Wells Fargo. The link between Bitfinex and ING Bank was first announced on February 14th by the Dutch newsletter Money.

ING Bank is closely involved with companies in the crypto money value chain

According to Follow the Money news, ING Bank can not reveal the value of Bitfinex's account due to privacy laws. Reusken said ING is intensively testing Blockchain technology and is very interested in cooperating with "companies in the value chain of crypto money."

However, ING spokesman Harold Reusken voiced some doubt about crypto-money. Reusken also pointed out that ING customers could not buy or sell crypto money through the bank, Reusken said:

We are very strict about companies operating in the crypto money market.

On January 30, 2018, Cointelegraph announced that Tether, the Bitfinex Exchange and its sister company Token, have been subpoenaed by the US Commodity Futures Commission (CFTC) for unexplained reasons. Cointelegraph today announced that Bitfinex has begun to raise Segregated Witness (SegWit) Bitcoin's scalability to all its customers before Coinbase, which plans to launch SegWit technology from the middle of next week to full launch.
