I mean plus like, what prosecutor is going to go after the people betting among themselves? That's pretty much unheard of when it comes to small recreational people. They're going to go after the people using setting up gambling clubs and rings, and the people running big programs like this. No one cares (AT ALL) about the little people that are doing casual gambling.
I personally know people who have lost everything due to a related incident. For some one studying finance you are pretty ignorant about how much destruction can be cause with the totalitarian financial regulations that exist in the US.
Not saying it doesn't exist, just saying the likelihood of it happening is probably pretty low.
You can do whatever you want when it comes to gambling online and all that, honestly it doesn't bother me in any way at all. You do you man.
