Twitter is a huge worldwide platform where public opinion can be swayed. Why would Russia waste time with their bot armies on a bitcoin forum? Without evidence it's probably not even worth postulating.
You will be surprised but their activity is noticed not only on global services such as Twitter or YT but also on absolutely non-political (but at the same time quite popular) ones. Let's say popular with teens Pikabu.ru which is Russian wannabe-reddit or Lepra.ru.
When you have almost unlimited budget you can cover a huge number of sites. But on the other hand I didn't claim that there are such users here too.
My entourage? What? I am American born and raised, and you are a loon.
If you read again you'll see that I didn't mean you personally.
Loon isn't the worse word people called me on the Internet.
