Today 104.5 JPY ~ 1 USD. 

Taking 1 BTC as 20,000 USD, 

We get that 1 BTC ~ 2M JPY, 

So 1 JPY ~ 50 Satoshi.

Thus, if 1 JPY = 1 Satoshi,

then 1 BTC == 1M USD.

This is by the 11/25/2020 USD:JPY exchange rate. It has fluctuated around 100 in recent history (source).

Maybe Satoshi Nakamoto was more clever than he let on. It certainly is nice to dream, yea? Or maybe 1M won't happen until 2140 and there will be something new by then anyway. Who knows? Gold is pretty ancient, and now we only use the value of its idea as currency to trade for goods and services. Does that mean we're breaking into a new digital cycle or beginning down a different path altogether? Gold is a really useful metal, you know, especially when it's not being used as a placeholder for some arbitrary value.

Maybe humans will find a way to trade real ether by 2140 😂

And we'll live in sky cities. 

But the Queen will try to accumulate all the ether to power her Mammon Machine, which lets her mine even more from Lavos and ultimately become immortal.

And the future refuses to change.

The true motives of Queen Zeal finally exposed.
