It's a bit worrisome that we are inching towards the scenario where companies may be tempted at an economy wide scale to reduce investment in production in order to hoard cryptocoins instead. It caused the great depression when businesses switched to hoarding gold tied currency instead of producing in the 1930s.

Now I'm not sure that crypto coins without being jacked up by central banks (like gold was during the great depression) are a powerful enough force to cause the type of havoc that gold did.

Then again, the potentially stronger network/memetic effects of cryptocoins, along with the amplification factor from markets being synchronized through instant all-encompassing global communications nowadays might make them dangerous to the economy even without central bank involvement. We saw how much people can get hypnotized by these things during the Gamestop episode. I don't think unsophisticated investors' hoarding is enough to cause big problems but it is a bit unsettling that Tesla and other companies are jumping on the cryptocoin train. If enough businesses follow suit, you get into scary territory (It would also be worrisome if companies widely moved to add billions in gold to their balance sheet but I thought the lesson had been learned in the 1930s with gold).

In theory, if central banks stay stimulative enough through all this, you can have growth in both crypto and businesses. As long as these central banks don't blink at the sight of what may look like crypto bubbles.
