It has occurred to me that we could start to use the term bitcoinaire in the same way we use the term millionaire today. A millionaire is someone who has $1M net worth (assets minus liabilities).
A millionaire is someone who has 1M and more in any currency, be it the dollars, pounds, yen etc.
The term "bitcoinair"is limited, because l if adopted will mean someone with 1M worth btc or more. What about someone with over 1M worth digital currency that is not necessarily "bitcoin", let's say ETH, will that person still be referred to as a "bitcoinaire"?
I think the most appropriate term for this is "Cryptonaire" that is someone with over a million worth crypto currency ( be it btc or any other).
