Sure, I wrote two newsletter post for my controversial takes (note, I am assuming this question is implicitly for people who understand that every "crypto" other than bitcoin is a shitcoin, and that the dollar will die):

tl;dr bitcoiners unfortunately may have higher levels of retardation than some may like to believe -- it could take many decades AFTER hyperbitcoinization for the foolishness to drain out before sound capital allocation really kicks into high gear. Stupid people getting poorer is the fundamental way that bitcoin works, but that process takes time.

tl;dr Bitcoin mining actually does waste energy, which is the entire point! Idiots like Saylor spew nonsense about bitcoin being energy, which makes people gloss over the hard physics that shows it is actually the least wasteful system, but just like a 100% efficient engine is impossible in the real world, you cannot beat Bitcoin's efficiency at what it actually does, which is information preservation with minimal loss.

Attempts to say the mining is good because it makes energy more efficient is giving in to leftist frame that subsidies are logical and that capitalism on its own is not enough i.e. it is sound money that fixes the grid, not the money 🤡...not to mention the levels of cuckery needed to simp for renewables. 🤡🤡🤡
