I think there was a frenzy around "Who's hiring?" this month on HN. (For instance, some people seemed to be running downvoting and/or upvoting bots aimed at job postings w/o salary ranges.) HN took measures to protect itself from overload and you might have noticed that.
Crypto has its own problems. The Bitcoin network is overloaded; probably at one point the issue was people motivated by greed buying huge amounts of Bitcons, pretty soon people will be like "Dude where's my money" and will create even higher loads pulling their money out.
