The big debate between CZ and this old man is actually quite interesting.

When discussing which is more reliable, gold or Bitcoin, the truth is that nobody knows how much gold exists in total, nor how much undiscovered gold remains in the earth’s crust. Diamonds can now be manufactured, and one day it’s possible that synthetic gold could appear as well.
If a few large gold mines are discovered in Xinjiang, Africa, or South America, the supply will change.

Gold’s supply is uncertain, but Bitcoin’s supply will always be 21 million coins, hardcoded and unchangeable by anyone.

This kind of scarcity: it doesn’t depend on Earth’s resources, government promises, or fear of technological progress, there won’t be any sudden “new discoveries,” and there’s no possibility of “synthetic Bitcoin.”

In fact, last week in Xinjiang, I had a heated debate about Bitcoin with someone outside the industry at a dinner table, because a new gold mine was recently discovered there.

I explained Bitcoin’s principles and mechanisms.
But he wouldn’t listen; he just kept insisting that Bitcoin must be an American conspiracy, waiting to harvest the whole world, and that it would inevitably collapse one day.

Like playing music to a cow😅

The past decade has already proven it, and for the foreseeable future, breaking Bitcoin’s hash algorithm—meaning the ability to forge blocks or alter the ledger at will—would cause the whole network to collapse instantly. With current human computing power, it’s almost impossible for Bitcoin to be cracked.

If someone could crack it, would North Korea put all its national resources into training elite hackers to infiltrate crypto companies and steal coins? Would Trump, as President of the US, spend his own money to buy Bitcoin?

Bitcoin is a free market asset, not a product that any one country can manipulate at will.
If the US could control it, wouldn’t it also control the price swings and mining distribution?
The reality is: miners are distributed across China, Kazakhstan, the US, Russia, and the Middle East; the hash rate is fully open and transparent; the code is open source and maintained by developers worldwide.
