So could it go to $1 million? Why not? All you need is for people to see it as a viable competitor to the US dollar, and some FOMO based around that. 500k would place it above gold in terms of market cap, this seems more likely to me although it FEELS a bit early. Not 4 years early, but early.

That's the main reason many people fomo in and loss all its money because they have the hopes that situation would happen but what they don't consider is the big impact it will have in stock markets for example,it will break at all markets and it's absolutely impossible it happens in these bull cycle. You may consider as well that government won't dollar continue losing power and they will try to make all possible efforts to increase its value again (even knowing that they will can't keep that situation in future) . If you zoom out and take in consideration historical data and some metrics about BTC the 500k or 7 figure it's impossible to happen still we get new halving season. Take care mate, greetings!
