~ and made me think about which will be the course of bitcoin if senators and other politicians talks about them?
It doesn't matter, he/she/they can't fight banks 
If anything is to come out from their "talks", that is tighter AML/KYC policies on exchanges and other financial institutions dealing with bitcoin, more regulations and probably more taxes on bitcoiners or crypto enthusiasts in general.
Don't keep your hopes up but do note that institutional investors might like all that ^ and might buy more BTC. To them, regulations means protection.
