I think, "being a decentralized asset" is what make a cryptocurrencies more powerful. No powerful entity or authority hold this; no centralized manipulation. The fact that is decentralized, we are also anonymous in our own way. No identification records in every transaction.
I do love this kind of invention, kuddos to Satoshi.
Agreed, Nobody did know until Satoshi emerged out of nowhere. In fact, nobody believed it was even possible. Satoshi proved it was. This innovation was to achieve consensus without a central authority. Cryptocurrencies are digital gold. Sound money that is secure from political influence. Money that promises to preserve and increase its value over time
