I agree with you that we’re all guessing, but what makes you think the crash is so far away?

“Never invest in a business you can’t understand” - Warren Buffet

of course he is right on this, but this only means you should try your best to understand, not to avoid investing.
another point is that i'm not sure that the Warren himself is totally understanding the topic he is talking about, it's a new game not like the old market.

He definitely does not understand it which is why he’ll never touch cryptocurrencies. In fact, he stays away from most technology all together.
And you’re completely right, the best thing to do is educate yourself. I definitely don’t encourage anyone to avoid investing in the market! Just avoid doing it blindly!
