You are right. There is a chance that this will happen. I just really doubt it. There is a very small chance it will happen. I think the max Bitcoin will reach is $10,000.
I agree, and even i think that reaching this amount $10k is not easy and may be need few years to happen if it's possible of course. But i don't think that bitcoin's price will reach $11M it's likely very hard to happen
If the bitcoin becomes a reserve currency, the price will reach $11m eventually. The US treasury is about $20 Trillion, divided by 20 m bitcoin, that is $1m for each bitcoin.
I'm not sure what you mean by "the US treasury is about $20 trillion", but the St. Louis Adjusted Monetary Base is about $4 trillion, so $4 trillion divided by 20 million bitcoins is $200,000 per bitcoin.
The value of a bitcoin will exceed $200,000 only if all the dollars are replaced by bitcoins (assuming FRB at current levels).
