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.
