On the positive side, even if we are in a bubble, the 2000 dotcom bubble was primarily a North-American phenomenon and yet reached $3–5 trillion in size 17 years ago. Cryptocurrencies are a global phenomenon and yet are currently only worth $300 billion — meaning the bubble has a lot of room left to inflate.
