Maybe also consume Twitter's firehose and use some combination of frequency of mention + some kind of influencer score (e.g., "verified" accounts and accounts with lots of followers are more heavily weighted) to determine hype. I've been wanting to built a sentiment analysis system for trading for a while now.

I almost made that mistake. I'd heard about it on Reddit way back when prices were $1/coin. Largely ignored it.

Next I hear it, it's on TechCrunch. Then on HuffPo.

I almost bought 10 coins at $500/coin.

By the time it hit NYT, it was $1k/coin

We all know how that story played out. Still kick myself for not buying like 10,000 of them at $1 though
