Interesting idea; thanks for posting.

Would be nice if the name/word could be associated with bitcoin, since the number 21 is already so familiar to bitcoiners and has inspired many projects, memes, start-ups, products, etc.

Also, you're asking this on SN which probably could not have existed without bitcoin.

I sense an opportunity to create a term that could capture some of bitcoin's value proposition, but without a marketing department - or any 'department' of course - to come up with a catchy phrase, we'll have to innovate here, I guess.

For example, if you search for "Magic Internet Money" today, you'll find many instances where this early meme about bitcoin found its way into all sorts of ventures - many not related to bitcoin. So I think something similar for 21 days would be great.

"Magic Internet Days" or "Magic Bitcoin Days" just sounds too copy-cat-ish, but let's see what other stackers can come up with!
