Claims like this are fun to talk about but little more than good marketing for Coinbase. (Don't get me wrong, I like Coinbase). But no one can say for sure whether bitcoin will have staying power and significance to be considered the world's reserve currency ever let alone 15 years.
What I think is a better discussion to have about this is why would we want Bitcoin to be the world's reserve currency. Existing fiat currencies are controlled and manipulated by Governments and Banks. Do you think these people are going to just let Bitcoin exist without their involvement or blessing? Do you think these people aren't going to want to have control and option to manipulate Bitcoin as they have fiat?
I think the answer is No!
If Bitcoin becomes the world's reserve currency, Bitcoin will be destroyed as we know it. I can't see a way that it wouldn't, but if you all think differently I'd love to hear it!
Bitcoins cant replace the dollar because the dollar is something other than the bitcoin and the bitcoin has no stable value and the dollar is always stable so better fgor people to carry on.
what this mean? bitcoin can be stable as the dollar if the market will grow, so it can eventually replace the dollar if this will ever happen, bitcoin is very small now remember this, so it need adoption first to take on major currency like usd and euro
