No way, Libra can't disrupt financial or economic system, it doesn't have such power. Actually, Libra hasn't achieved any success at all and failed according to all expectation. Also, it will not become world currency. And what exactly that means, that will be officialy used in countries all around the world? I don't think so.
Exactly. Right now, Libra seems to be an idea than anything else. It won't be able to make it before launch as governments are already against it. Facebook will have a hard time trying to "disrupt" the economic system as we know it. Given that hopes for the launch of Libra are lost, I believe that another cryptocurrency will take its place in transforming the world's economy for the better. It could be another stablecoin issued by a widely recognizable mainstream company, or simply government-backed digital currencies issued by worldwide central banks.
Even bitcoin is incapable of being the world currency and so the non-existent yet Libra could not too. Really facebook? After having such big scandals that associates with data breaching, your next move is to make a cryptocurrency? As far as I know Zuckerberg is facing still these recent anomaly in court with facebook. If the world is ready for cashless, then someone big will arrange for it, surely it is not the facebook, maybe the richest nation by that time. And for sure thing it is backed, stable and secured.
Believe me, it's not about cryptocurrencies but rather Blockchain technology itself. This same technology has attracted the likes of governments, central banks, and businesses alike because of the benefits it provides. Any cryptocurrency can come up with new features and an attractive supply, but if it's highly centralized or more of the same, it'll fail in the long run. The core Blockchain technology is what matters nowadays, and if mainstream companies and governments put it to good use, they'll be able to disrupt our economic system in the future. But this will greatly depend on how much people are willing to adopt this system within the mainstream world.
China has already in process of integrating blockchain with their current system. What they are doing recently is tracking down illegal and fraudelent organization to basically start their initiative on upbringing this one. Blockchain is the next big thing, I'm starting to see online banking with the help of blockchain that could help banks and consumers with ease.
Nonetheless, there's no doubt that Libra will fail in disrupting our economic system. But Blockchain technology will succeed one way or another within the not-so-distant future. We'll have to be patient to see how worldwide governments will adopt a regulatory framework suitable for the growth of the entire crypto industry. Only then, we'll see the "green light" for centralized digital currencies with the aim to replace the old Fiat system of today. Just my opinion
As for current relationship of every country, the change we want might come longer than we think. But atleast we have a vision and mission now.
