Now, I think Zuckerberg may feel doubt to continue Libra project because still no positive progress to get permission from US government.
Libra is based in Geneva, Switzerland.
In theory, they don't need the permission of the US Gov.
Kinesis launched last September even if they still haven't the permission of the US authorities.
But as the US would be their biggest market, in practice they need that permission.
Zuckerberg is unlikely to succeed. Too much confidential information will be concentrated in this social giant, and financially it will pose a threat to all developed countries of the world
Social giants have already plenty of concentrated confidential information.
Our Govs don't care about it, they never cared about it, just as they don't care and never cared about developed countries.
What they care about is money, being in control of the global money supply.
but if we talk about cryptocurrency, privacy is the main goal of cryptocurrency,
For me, the main goal of cryptocurrency is not privacy but to eliminate the power of the banks over my money and that of the people.

There's no other way, they really have to convince these regulators before they launch.
Indeed. There is no point in launching a cryptocurrency aimed to the masses, without regulators' permission.
The project will die 3 hours after launch.
Kinesis postponed several times their launch because of regulatory issues. Up until today, US citizens still cannot invest in it.
One of the main issues for these projects which want to be global and widespread, is that they need the permission of regulators of a whole array of countries, at least the major ones.
Plus, at the moment the legislations about cryptocurrencies are fluid, mostly absent, the future regulation is unpredictable.
Even the regulators don't know how to behave. They lack rules to base their decisions with.
We are at the beginning of a new financial era.
