we aren't there by any means, a trillion is 1K billion in the short scale, and we are still at a mere 4B
we need to do a x250, which mean a price of 62.5k, something a bit crazy, that won't be reached before 3 halving at least
an interesting thought by Winklevoss twins that Bitcoin as a payment system will surpass visa+mastercard+amex+ other major payment systems= 400 Billion$ and be in Trillions of dollars
https://youtu.be/uEIPzl4Bx5I?t=137 , so primarily it is a point of time when people start switching from these payment processors to Bitcoin, it should reach the average Joe's throughout the world from a Hotdog seller in the US to a peasant in India., thats the time probably Bitcoin will reach a trillion$ market cap.
I wouldn't place much faith in WW brothers, they seam to be easy on words in most cases, but on this one ill give them credit.
There's no reason why bitcoin shouldn't replace most, if not all other alternatives. It's just a matter of time and struggle it will take to get there.
But i must say, expecting prices of 60k+ is a very far dream, and even if it is to happen, it wont be anytime even remotely soon.
cheers
