Any value system needs sufficient distribution. A coin that is owned only by one guy or a couple of guys is worth nothing. They have the problem with USD and with any other shitcoin. If there is vanishing demand for a currency it collapses.

Only Bitcoin (so far), Ethereum? and Monero have seen widespread distribution. Outside if that it's only speculation.

Making Bitcoin less distributed beyond a certain point will make it less and less interesting.

Using leverage to buy it with worthless fiat is another story that won't collapse Bitcoin. It'll ust produce another volatile cycle which is good for speculators but further hinders use as money.

I don't know which lodge exactly, yet. But this is far to elaborate and tolerated to be the play of a single CEO.
