Harvard economist Kenneth Rogoff admitted that he was wrong with his prediction. But it did take him 7 years to admit he's wrong. And probably took his time though and come to his senses that Bitcoin will go and compete with any other assets that is known to man.
He never said he was wrong about Bitcoin. Still sees Bitcoin as what he saw it decade ago
What he admits being wrong about is the government stance
We all know his prediction was wrong, he's trying to justify why he was wrong
And almost felt like Bitcoin success was because the government allowed Bitcoin to succeed.
