To be honest, I am not familiar with how blockchain's work, or whether or not this is a good idea by Robert F. Kennedy, Jr. What I do know is that it brings, or has the potential to bring cryptocurrency to the minds of the public in a meaningful manner. 

Here is an article outlining RFK Jr's 's statement in more detail:https://thehill.com/business/4611426-rfk-jr-im-gonna-put-the-entire-u-s-budget-on-blockchain/ 

Apparently, the gist of this recommendation would be that budget would be available to the public, and it would be transparent and help to hold the government to be more accountable for spending. Now, in theory, I love this. I mean, the government being held accountable would be great. I for one am tired of people working in government regulating everything but themselves. 

In a more practical manner, I am not sure this would work. Would there be security risks? Would it be able to be manipulated? Again, I do not know or understand the technology.

Another point that I think is important is that RFK JR. will not be elected president, so the point is moot from a real life standpoint. But from a discussion standpoint, to bring awareness to this issue, I think RFK Jr's points are valuable and helpful to cryptocurrency in the long run.

Mainstream crypto is coming, and it will bring untold value to those early adopters, let alone the value the technology brings in and of itself!
