Warren Buffett is plain and simple, with enduring investment principles: don't touch overvalued assets! He would rather hold a huge amount of cash for three or five years than do something foolish.

Now the GNS and GMX in the crypto world have a market yield of about 5 times, which means that staking can earn a 20% annualized dividend income. In 5 years, it can earn 100%.
The stock market has never had such a good thing. The stock market usually has a 20x multiple, and there are rarely 10x market winning rates.
