I still suspect the real reason for this sudden change of sentiments is due to the global chip shortage. The major players must have some intel that we don't, and that's really the only way I can make sense of Tesla's decision to criticize BTC's energy usage. They know for certain that bitcoin's fundamentals are rock solid, and that its PoW-based energy usage is not problematic at all.
The idea here is that Tesla operates in the EV market, so they absolutely need chips to keep up with production. It'd make sense for them to try everything they can to get those semiconductor factories back to exporting chips. They must be desperate, and that's why they decided to risk doing such a silly move, as far as PR and marketing goes. Because however you look at it, it's a weird move that sends a weird signal to the market.
I suppose their reasoning was: "all the chips in the world must be going to bitcoin miners, and if this keeps up we'll go out of business for months, so let's try to crash bitcoin with a tweet lol".
Whatever happens, nothing changes fundamentally. Before Tesla jumped on bitcoin's bandwagon, and despite Munger's comments about bitcoin's civilizational role, it already made sense to buy and hold bitcoin as far back as 2018.
However, public opinion and news reports seem indeed to be changing their tone.
So in my view this will trigger either the bear trap, and BTC will soon rally up to double its valuation, or the start of a larger crash, and BTC will go down as much as 80%. My strategy will be similar in either case: hold my ground.
Not financial advice. Just some sci-fi logic. DYR.
