Always the same old stories, but we should not forget that the audience is changing and that it sounds very interesting and new to some, because they are beginners who need advice, guidance and vision. According to CZ, the average investor is not intelligent enough to be his own bank anyway, and instead of teaching them about it, he advocates a custodial service because it suits him personally.
