You could see the history of the satoshi and while it was once very cheap and has appreciated more than anything else, it's still insanely cheap! You can buy millions for next to nothing! I have this strange suspicion that if coinmarketcap did this and a lot of the exchanges folks, folks would start buying like mad. As soon as I introduce someone to bitcoin their first thought is, "yes but it's so expensive can I just buy a cheaper alt?"
Clearly bitcoin doesn't have to change, just the reporting of it's total numbers and the value. That's it.
This is honestly not a bad idea. It's just like the mBTC proposal except on steroids
The reason why a lot of altcoins are being pumped heavily right now is solely due to the fact that people FEEL like that the price is still low, even though the supply may be way higher than they think. It's weird because it seems to be common sense to everyone that going from 5 cents to $5 is way easier than going from $5000 to $500000, even though it's the same percentage increase.
I think that this is probably not going to happen, because it'll require a hard fork to essentially inflate bitcoin's monetary supply and dilute the worth of each bitcoin. It's best to just get wallet services to use satoshi as an option. They currently offer bits and mbtc, but surprisngly not satoshi.
