Here's an interesting chart that gives visual estimates of the world's cash, crypto, gold, real estate and other assets. It's a quick, simple, and slightly mind boggling estimate of the world's total wealth.
Taking a look at this chart can help you get a good estimate of where crypto is going. I personally believe that "bubble" warnings are far too early. For reference, the dot com bubble peaked around $10 trillion. Nowadays, Apple alone is worth nearly $1 trillion.
I think that crypto will reach $15 trillion before any chances of a crash occur. The current crypto market cap is around $500 billion. So, we've got a long way to go and lots of money to make. What are your thoughts?
