Whether any are a good follow, I couldn't tell you but names in a comprehensive anti-bitcoin list will include:

• Frances Coppola (journalist, thus has economic incentive to be anti-bitcoin)
• Peter Schiff (sells gold, thus bitcoin is a competitor in the store of value asset class)
• Alex De Vries / @Digiconomist (central bank staffer, will spin whatever he can to persuade you that bitcoin mining is bad)
• Cas Piancey and Bennet Tomlin, Crypto Critics Podcast
• Tim Swanson / @OfNumbers
