Right after the attack to OKEx was contained, the exchange Bitfinex was attacked by a sophisticated DDoS, according to a tweet from Paolo Ardoino, the exchange’s CTO: “I was not aware of the attack against OKEx yesterday.

Coinbase publishes strategy to prevent Coronavirus

The coronavirus is spreading itself at a scary speed and is causing negative impacts that go way far from the health area. Segments like industry, tourism, and commerce are already being affected by the dissemination of COVID-19 and are provoking huge economic impacts globally. The cryptocurrencies are also being affected, with Bitcoin’s price falling by 3% after the detection of the virus in Italy. 

Various businesses are preparing themselves for the worst scenario and the exchange Coinbase is one of them. According to a document shared by CEO Brian Armstrong, the exchange will be preparing responses of scale in 3 phases. Each phase will be activated according to the increase in the number of infected people or by quarantine declarations by local governments. 

Phase 1 will be activated when there are over 100 confirmed cases of “virus transmission from people to people”. The Coinbase will authorize, in this case, its employees to work from home and will increase the frequency of the cleaning of the offices.

Phase 2 starts when there are over 1000 cases like phase one confirmed or if there are any quarantine declarations. In this case, the Coinbase won’t offer meals in the offices anymore and won’t’ allow any visits to the offices. On Phase 3, the most critical one, the employees will be obligated to work from home and services like cleaning or meals in the office will be suspended for an indeterminate time. 

The Coinbase has offices in the USA, Japan, Ireland, and United Kingdon, and Phase 1 is already activated in Japan.
