Well, "Bitcoin" would obviously be one of the lyrics.   Other than that, not so much.  I consider song writing (as opposed to, say, music theory) as my greatest musical capacity and I typically write my songs as I go (continually revising, of course), so I honestly wouldn't really imagine having any specifically great ideas until I was already in the middle of the process.  I would also likely write the lyrics last after I have written and completed recording the song.

I really like the first song that was posted.  I mean, I REALLY like it.  But, in my opinion, it gets a few minus points for sounding too much like the Beatles (I actually don't really like the Beatles; they kind of bore me, but this song is pretty) and it also gets a few minus points because I swear they did almost a direct copy of that "down....down" motif.  Not sure where I heard it, though.

I do agree there is room for more, and perhaps this leaves open the possibility for a "Pac-Man Fever" type of song, one in which the word "Bitcoin" is repeated throughout the song, and one that is more geared toward the "novelty" side of things...the kind of song that might get 1,000,000 hits on YouTube in a week and then zero after that.
