As Bitcoin or Cryptocurrency users, is there any way we can oppose this? Any way non EU members can help by opposing this law or does the voting and all happen among these fossil leaders and decision makers out of who most have no idea how Bitcoin even works?
EU citizens can write or call their representatives in the European Parliament, but whether or not that makes any difference is anyone's guess. The European Parliament strikes me as the kind of institution where the representatives care even less about the views of the people they claim to represent than national parliaments. As for people outside the EU, there is probably nothing you can do directly unless you want to pretend to be from the EU and email them anyway. Maybe contact exchanges which operate in the EU and ask them to actually fight this rather than roll over and accept it and sell out their users like they usually do?
