26 November 2017   837

On November 26, Bitfinex, the world's leading cryptocurrency exchange, reported on Twitter that their website had undergone a DDoS attack and the provider is doing its best to solve this problem.

It was reported that the DDoS attack started during earlier maintenance and has been ongoing since that moment. DDoS attacks disrupt normal operations by degrading website and application performance and availability, sometimes knocking them offline completely and the average hourly cost of downtime due to an infrastructure failure is $100,000 per hour.

Previously it was reported that on 21st and 24th of October Bitcoin Gold was under DDoS attack twice too, but BTG team managed to solve this issue. 

Bitfinex Banned Margin Trade For US Corporate Customers

This news is reported by the margin traders themself at Reddit
15 February 2018   50

One of the largest crypto-currency exchanges, Bitfinex, suddenly closed access to margin trading for corporate clients from the United States. This is reported by Bitcoin.com.

Some corporate customers of Bitfinex expressed their discontent on the Reddit after they found out that their access to the marginal trading was closed. At the same time, restrictions imposed at the end of last year in accessing the services of the exchange concerned only US residents who are private individuals. The Bitfinex knowledge base also says nothing about the restrictions for US corporate customers.

We’ve had a corporate account with Bitfinex since early 2017 and [are] approved for both exchange, margin, and funding. […] We’ve been making 6-figure trades on margin and currently have 2 margin positions open. On Feb 7th, […] we were locked out of margin trading. No explanation or warning of why our account can’t trade on margin. Worst yet, we can’t manage our margin positions. Not good in this very volatile market. We’ve received a couple of liquidation warning emails as the market dived down yesterday. We sent a support ticket […] and probably over 7 emails. No response from Bitfinex. It appears that they haven’t even opened any of the emails.

Later that day, a Bitfinex representative called “bill_bfx” contacted the Redditor, stating that the issue had been “forwarded to the team to resolve for you.” 

a US corporate customer […] should not be using margin trading,” however, noted that “if you have open positions it is not acceptable to block you from closing them.

Another Reddit user reports:

I’ve been lending on Bitfinex for a while. Earlier today, the API responded that US users are no longer allowed to take or lend any currency denomination […] I understand that US retail customers cannot use it but I believe the policy did not apply to corporate customers. Has there been a recent change in policy? Will it be permanent or is this a temporary measure?
