Good q.. This is first book I'm aware of that covers the ETF effect in depth, which in our view was a total game changer as it solved the ongoing intermediary problem for bitcoin/crypto (by making it much cheaper and much safer) and opened it up to $40T of financial advisor money. Second, the majority of existing books generally written by die-hard evangelists or the opposite- journalists looking to exploit/mock the characters and hijinx in the space. We wanted to give readers a more middle of road, pros and cons type book for someone considering a sattellite allocation. We also have all the latest progress in tokenization which has evolved a lot in just a few yrs- as well as a TON on debasement and debt (which is easily one of the most impactful issues in country- and world) which is also evolving quickly. So there's a lot new imo. But yeah, some of the book def covers already-trodden ground.(Eric Balchunas)
