Yeah, Shelby / anunymint quoted for being a pie in the sky dumb-ass might be appropriate. There are definitely bitcoin naysayers out there, like Shelby/anunymint, jonoiv, and others, who are wishing either that bitcoin has not transitioned out of its previous bear market (of 2018) (seems like decently odds of well-less than 40% of going back into a bear market now), and/or that bitcoin will experience a convincing technical obstacle, such as the bullshit lack of segwit adoption attack scenario, that anunymint continues to spout off about (seemingly less than 5%), which will cause BTC prices to fall or some other currently stupid-ass scam coin (such as bcash or ethereum or some other largely smoke and mirrors project) to take up some of bitcoin's networking effects to become the credibly dominant coin.
Well, I don't place as much certainty into Shelby's recently published scenarios as does he. But if you are going to criticize his ideas, you'd look a whole less stupid if you actually read what he wrote, instead of inserting your own flight of fancy and attributing your way-off-the-mark statements as his.
