Warren Buffet doesn't really do tech analysis.
My friend is really into Buffet and he says that buffet's main rule is: Don't buy something you don't believe in or understand.
And that's the gist.
In buffet's book, he just diversifies his investments and only buys into stocks/investments that he understands and believes in.
I believe if we all followed that path with crypto, we probably would find our 100x.
That said, Confido was something people could've detected if they used this rule. Confido had broken links and no working examples. But the website had promises and good development.
Most people in crypto just jumped in because they trade on headlines instead of on fundamentals.
Buffet doesn't do technical analysis of stocks, he does value analysis of companies. That's not the same thing. People who do technical analysis focus on nothing about the company and everything about the stock movements and trading patterns, almost in complete regard for the underlying company. Buffet is a pure capitalist. He analyzes companies looking for what is undervalued and he can make more valuable by buying and bringing efficiencies or capital to. Buffet's story is much more about the efficient utilization of capital, what can he do with his money that will earn the most return? That approach necessitates knowing what you buy, which is why he stays away from technologies and industries he doesn't understand.
