My small brain says that it's so improbable for
BTC1 = $1 billion as proclaimed,
https://bitcointalk.org/index.php?topic=5454591.0BUT if we're lucky enough, I would suggest that you keep that you're HODLing Bitcoin only to yourself, not even your relatives and close friends should know. Believe me, wealth doesn't entirely change the person who made the wealth. It changes those people around the person because they know he/she has made wealth.
In my personal experience the "wealth change" wasn't that much during last ATH, but if Bitcoin surges to $1 billion, I probably should go into hiding.
The precious thing about bitcoin is that even if you hold a billion dollars worth of Bitcoin, no one will know crap about it since Bitcoin is highly private and untraceable unless the holder exposed his ownership of the wallet holding the Bitcoin.
For beginners like us, we still keep accumulating more Bitcoin even if the price gets as high as 1 billion dollars since my current Bitcoin balance can't earn me your kind of luxury even at a bull market price.
