I'm not buying into the conspiracy theories here. All of those guys are free thinkers who made money doing their own thing. They just don't like bitcoin. They know what it is, believe me, and it's not for them. They're entitled to their opinions, even if everyone on this forum disagrees.
Bitcoin has a lot of disadvantages that tend to get overlooked by members here, and if you wonder why it hasn't been adopted by the masses yet, it's because the masses don't need bitcoin. People get so emotionally attached to bitcoin that they fail to see that it's not really solving many real-world problems. Buffett, Munger, and Gates don't make that mistake. All three are very rational and just don't like bitcoin--so be it.
You can always take this perspective. You can say things are just as simple as they appear in public, and it's hard to prove you wrong. Whether there is a deliberate (dis)information campaign, we really have no evidence either way. What I try to do is to look at incentives.
I would disagree with 'Bitcoin doesn't solve real world problems,' however. Bitcoin is the new gold (not entirely, but largely.) The elites clearly prefer something like a gold standard (they just won't say so at this point!) Whether it's good or bad for the economy, it does provide for more stability compared to 'totally fiat' money we have today.
The reason Bitcoin has come this far may well be due to behind-the-scenes support by the top Western elites, who would like to return to something like the gold standard, but don't have enough gold to do it (or have to devalue currency against gold to an extraordinary and embarrassing degree to obtain any stability.)
Bitcoin only does one thing new, and that's decentralization. It's a poor store of value due to instability in the price, it's an even poorer currency for the same reason. When he says Bitcoin doesn't solve any real world problems, it's acknowledging the reality as it is right now. The best you can say about Bitcoin is it has potential to change things, but nobody who needs to conduct day to day commerce is taking Bitcoin seriously. To the extent it's used at all, it's to appeal to the niche part of the market that wants to use it for transactions. Bitcoin hasn't proved any ability to be the new gold, the best you can say again is that it has potential, but it's much more of a speculative asset than a store of value.
Bitcoin can't even hold it's value for an hour, the notion that it's more stable than the USD is idiotic. Sorry, there's no sense in sugarcoating that. It's absolutely absurd.
No elite prefers the gold standard because the fiat standard is what made them wealthy. The gold standard was abandoned because it constrained the economy by limiting debt-fueled growth. It wasn't until the abandonment of the gold standard that you got this explosion of ultra wealthy elites, and since the abandonment of the gold standard, the wealth accumulation by the top .1% has really accelerated relative to the rest of the populace. It defies logic they would abandon the system that created their wealth to a larger degree than the gold standard would have allowed, so if you want to sell that, you need to provide some substantiation, because it's not a compelling theory.
