Se prometió que Bitcoin, BTC, sería una tecnología liberadora, una alternativa de libre mercado al dinero controlado por el estado. Pero esa promesa se rompió cuando un pequeño grupo de individuos con información privilegiada se hiciera cargo del proyecto y cambiara fundamentalmente su diseño. La verdadera historia de BTC y su diseño original la conocen muy pocas personas debido a años de fuerte censura, ingeniería de redes sociales y estrictos controles de información. La realidad es que BTC ha sido secuestrado y cambiado para peor. Esa es la conclusión innegable de El secuestro de Bitcoin, un libro repleto de historia y verdades incómodas, que descarga una andanada desmitificadora contra las narrativas más populares que rodean a BTC. Roger Ver es el primer inversor del mundo en empresas emergentes de BTC y ha sido un nombre destacado en la industria de las criptomonedas desde su inicio. Sin embargo, como confiesa en la introducción, este libro no es una historia de amor. Es la exposición devastadora de la corrupción, la propaganda y la centralización del poder en BTC.
