For 1 Bitcoin to be worth $1,000,000, the total market cap of Bitcoin would have to be $21 trillion dollars. What are the odds of this happening?
For reference, the amount of physical $dollars and coins in circulation are around $1.2 trillion. The global M2 money supply of all currencies are around $45 trillion. The market cap of all mined gold is around $7 trillion.
Will 1 Bitcoin be worth a million dollars? Half a million? Thoughts?
$ 1 million for a Bitcoin, which I previously did not find reasonable, but after the exchange rate of the BTC just then I see this is perfectly reasonable. And as Sir McAfee predicts, by the end of 2019, BTC will reach $ 1 million, so I predict that by the end of 2018 the BTC will reach $ 500,000. So you should invest in BTC right now to be able to make big profit next year.

No, I remember he said 1 million dollars will enough to buy 1 Bitcoin in 2020, I do not remember he said 1 BTC = 1 million dollars in the end of 2019. $500,000 for 2018 is not impossible, but it is very high price to raise. I think $100,000 or $200,000 will be the highest price of Bitcoin in 2018.
