Isn't a 24-word seed phrase overkill? Is 12 words fine?

Just got my first Ledger, and it defaults to a 24-word seed phrase.

AFAIK, it would take a trillion computers, guessing a trillion times a second, for the lifetime of the universe, to brute-force a 12-word seed phrase. A 24-word seed phrase seems like overkill.

While I will be carefully storing my seed phrase, I also plan on committing it to memory. I have some experience with this, and 12 words is doable. But I'm not so sure about 24 words.

I'm considering making a 12-word seed phrase wallet, and restoring the Ledger from that.

So, is a 24-word seed phrase overkill? Is 12 words fine? Is there something I'm not thinking about?

Coinmarketcap are listing BCH sites as BTC

Under here: https://coinmarketcap.com/currencies/bitcoin/ They have links to https://bitcoin.com/ and https://forum.bitcoin.com/ which are no longer BTC sites; they're BCH sites. I'm not good at twitter and don't have many followers but I've tweeted at them here: https://twitter.com/bitplane/status/955918445014585344 Can we raise awareness of this and get them to change it please?

15 years of BTC Power Law

5 years ago I made a post in this subreddit showing that BTC is a power law: Price=A*days^n, (days from Genesis Block), n=5.8. Many didn't believe me and said the past doesn't predict the future. Well, after 5 years it turns out that BTC continues its power law behavior with similar exponent. A power law is not another formula or model but the same mathematical behavior behind river formation, mountains growth, cities development, GDP vs population, and metabolic rate. Everything important is ruled by power laws, so BTC. BTC is a force of Nature.
