In the US? Elizabeth warren. Not only is she loud and annoying with her criticism, she continually introduces bills to congress to make it harder to use Bitcoin or downright impossible. Her statements also shape liberal perception of Bitcoin and provide talking points to her allies.

Which is why I donated money to her primary opponent. There is zero chance of a non-dem winning her district. There is a decent chance she could be unseated if her primary challengers have enough backing behind them. There's a few bipartisan pro-Bitcoin PACs, I donate to them too.
