Either. Spinning up a cryptocurrency may become as mundane as creating up a database, as silly (or illegal) as trying to market a Ponzi-based hedge fund, or simply a pedagogical tool for CS students.
There is nothing inherent to crypto that says it must hold value. Markets are moody.
Yet you will find claims, on this thread, that Bitcoin becoming worthless is not possible.
A company’s stock (or bond) is a right to get some compensation in case of dissolution, bankruptcy, or liquidation sale. A precious metal like gold still has a backstop value - it can be sold to electronics manufacturers to make those beautiful gold-plated audio cables. Diamonds have a backstop value of being used in boring and drilling. Vacated real estate can be converted to other uses.
All of those assets (when owned outright and not pledged) are unlikely to go to $0.
I'm not sure what difference this makes.
As you can see here, Google has billions of assets, of which $19.7 billion are buildings.
Edit: I thought I posted a link to Google's balance sheet in my parent comment, but apparently I left it out: https://www.marketwatch.com/investing/stock/goog/financials/...
