Can BTC restructure a new financial order? Can BTC or another kind of cryptocurrency beat down the U.S. dollar? What's your opinion?
It can't establish a new financial order, because it doesn't have enough users, it's estimated that 0.5-2% of the global population use Bitcoin, and they don't even use it on a daily basis, most of them just hodl, trade and very rarely pay. Bitcoin is already 10 years old, and in this age new things get picked up almost instantly, Twitter, Facebook and other services got millions of users in their first years, If Bitcoin didn't manage to get big now, there's a good chance that it will never become big.
From what I see Bitcoin will always be more of a tool for a specific purposes, like avoiding banks when you have a good reason to, cheap international transactions, decentralized store of value, microtransactions with LN.
