Due to the overwhelming surge in popularity, Binance will have to temporarily disable new user registrations to allow for an infrastructure upgrade. We apologize for any inconvenience caused.
CEO of exchange reported on huge wave of new registrations.
sorry guys, servicing existing members is higher priority at this point. Full team working around the clock. Both tech and support. Just too much demand. Added 250,000 new users in the last 24 hours. Just crazy! https://t.co/yY8eCIL2Ph

Earlier in December, Bittrex stopped new users registration too. The reason is same - "large spike in new user sign ups."
