Speculation: There will be XMR billionaires by the end of next year. Wrap your hear around THAT one.
I wouldnt go that far. I mean even if it quadrupled in price (hitting 600$) then in order for somebody to be a billionaire then theyd need to be holding 250 million dollars worth of Monero. Even if it went 1 thousand times you'd still need a million worth of XMR to become a billionaire.
The growth in crypto prices has become much like most other current technology growth in that it is exponential in nature. So, in many ways we become very short sited and conservative when we look at where we expect prices to be in the near future because based on our experience with most things, we expect grow to be linear. The growth curve goes parabolic and you may have started with $3,000 investment which has maybe grown to 30 times what you invested up to $90,000. Now if that trend continues which I don't doubt that it will and it grows another 30 times you have $2.7M! There are many here who have invested anywhere from $10K to $?00K and from an early stage on held onto that stash.
It is totally conceivable that some are holding 100K to 500k xmr but because it's Monero we can't tell that for sure but, if it were true, tell me how long before that adds up to $1B?
The point is this is exponential in nature NOT linear.
PS. the numbers are examples, I didn't pull actual growth rates.
