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.

The Hong Kong cryptocurrency exchange Bitfinex has listed the so-called Chain Split tokens for the two implementations of the Bitcoin Cash protocol. Bitcoin Cash hardfork is planned on 15th of November.

BAB [Bitcoin ABC client] and BSV [Bitcoin SV client] tokens will be traded in pairs with Bitcoin and the US dollar. The Token Manager tool will allow users to convert their Bitcoin Cash into one of the tokens. This process is reversible, Bitfinex emphasized. At the same time, marginal trade in tokens will be unavailable.

After snapshot of the network, the corresponding coins will be automatically converted into BAB and BSV onchain tokens, and all current Bitcoin Cash holders will receive an equivalent number of coins. However, if the user has a short BCH position at the time of the snapshot, the margin will be canceled, and the borrower, if he does not have enough tokens, will have to cover the negative balance sheets until December 31.

Bitfinex also warned that support for BAB and BSV could be temporary, and that as soon as all negative balances were covered, the exchange could delist them, allowing limited time for withdrawal.
