Continuing the analogy, the meme in the early 90s was, “on the Internet, nobody knows you’re a dog.” But that changed quickly once e-commerce and advertising began to provide an incentive for pervasive tracking and data mining. Bitcoin anonymity today is where Internet and web anonymity was in the 90s — a variety of research papers have shown how users’ pseudonymous Bitcoin addresses can be linked to each other and potentially to their real-world identities, but it remains to be seen if linking/tracking services will develop and flourish. It would be entirely unsurprising if they did.
— The importance of anonymous cryptocurrencies
Ne pas oublier que l’historique des transactions Bitcoin est public, à vie. Est-ce qu’un jour une société aura suffisamment d’informations pour tenter de tracer en partie l’usage et l’état des finances de tiers ? Franchement loin d’être impossible.
Bitcoin est d’un côté bien plus anonyme qu’un paiement par carte bancaire, mais d’un autre côté potentiellement aussi plus dangereux sur le long terme.
