"guru"...whatever
If you constantly repeat something someday your prediction will happen.
The best example is Roubini.
He predicted the crash 5 times before it happened, he nailed it at the 6th attempt and since then he is constantly wrong, I think the number of fails is over 20 so he turned bullish in the last years.
Your "guru" is not a liar.
He is just a guy guessing stuff based on the weather outside and he is really bad at math.
If i'm going to tell you
BTC will probably raise to 20 trillions will that make me a liar?
Let's wait and see. We can even have a bet on this.
Am i the first inteligent person that just doesn't repeat what opinion leaders in crypto say... and thinks, calculates and verifies for himself??
Don't rate yourself too much.
Most of us don't even bother listening to those guys.
They feed on likes and retweets.
wow seriously... you have never heart about him...? But you surelly heart about Max Keiser, Rick Falkvinge?
Wow, Max Keiser...the guy that is always wrong...
And the father of a total failure:
