Don't worry the bear will be back in 30 days. That's when Google adsense's ban takes effect.
When the ad ban takes effect it's just that a few ICOs and platforms will not gain publicity through ads. That's it. It doesn't necessarily mean that when the ad ban comes that people will be selling crypto due to fear. It's just the ads. Not that significant if you ask me. People are making it too much of a big deal.
On the other side though all the people that get phised by clicking on Google ads for fake sites (I know somone who lost $2K on a fake shapeshift site) will go down massively. Which is a good thing.
