I think it's a bit premature for that, in terms of purchasing power. When BTC has large enough purchasing power to actually compare to a major currency, we can talk. But the economy is still tiny for now.

The delusion is strong in this one.

A "bitcoinaire" is good enough since 1 BTC will be more than 1 millions $ in parity purchasing power 

Millionaire means nothing anymore. I have several million... pesos.

In the English language it usually refers to having a million dollars, pounds, or euros. It usually does not mean having a million in currencies with significantly deviant unit values.

It's kind of weird that we're stuck with millionaire, today 1 Million dollars isn't really all that much.

To me it would be a lot but I'm smart with my finances and I don't buy useless fluff. (Not all the time at least).

1 Million dollars is like 67 years of minimum wage (which is a shitty definition of a rich person)

Or maybe 20 years of a fairer minimum wage (still not the definition of rich).
 

+1 for bitcoinaire

What about a 10+

If you are a 1+ you have over a coin and if btc goes to 100k being a 1+ will make you rich.

So a 10+ would be todays millionaire with btc over 100k.

that thought makes me depressive...  

Bitcoinaire sounds really awesome!
But, getting back to OP, in some countries, depending on the buying power of it's currency, you need to be a 'billionaire' in order to be wealthy. It's all relative to what you can buy with a certain amount of monetary units.
