Опять двадцать пять))) такого что только банки биток держат не написано. Биткоин это деньги для всех людей)
Специально посмотрел фрагмент из книжки:
Such an analysis may contradict the rhetoric that accompanied the rise of Bitcoin, which promotes Bitcoin as putting an end to banks and banking. The idea that millions, let alone billions, could use the Bitcoin network directly for carrying out their every transaction is unrealistic as it would entail that every network member needs to be recording every other member's transactions. As the numbers grow, these records become larger and constitute a significant computing burden. On the other hand, Bitcoin's unique properties as a store of value are likely to continue to increase demand for it, making it hard for it to survive as a purely peer‐to‐peer network. For Bitcoin to continue to grow there will have to be payment processing solutions handled off the Bitcoin blockchain, and such solutions are emerging out of the grind of competitive markets.
И дальше там про банки пошло. Слижком уж много копировать
