I'm pretty sure they have advisers even though they are already seated as legislators and regulators. These advisers can explain to them what cryptocurrencies are in a concise manner without overwhelming these grandpas that you speak of.
That was my second thought about OP's post. These "grandpas" don't really have to understand the mechanics of cryptocurrency for one thing. They probably know enough of what bitcoin is (a bank-less, government-less currency) to make decisions as far as regulation, and whatever they don't know, they certainly aren't working alone in making decisions. Every congressman has advisors and teams of information-gatherers, so I wouldn't write them off just because of their age.My first thought was that being 60 years old doesn't make you ignorant of technology necessarily. Crypto is certainly a younger person's game, but these people high up in government are generally not stupid people. They're usually quite intelligent actually. Your grandfather might not know how to use a cell phone or the internet, but that simply isn't true of all senior citizens--and 60 years old doesn't even make you a senior citizen anyway.
People are not elected to make laws for their expertise in whatever industry, but they are elected because they have the capacity to act on behalf of the interests of the people they represent, and they are fair and objective in their assessments. You can't expect congressmen to know everything about every law they have to examine.
Yep, all of that is true. I'm not a fan of most politicians, but I don't hold their lack of expertise in various fields that they end up regulating against them. They're not working totally in the dark on these things. 
. I accept one thing, these old politicians might no have much idea about the technology but they will hire advisors and other professional bodies to formulate a draft bill and then there are many procedures they to need to undergo before coming out as a law.
