Cryptocurrency is a kind of digital currency, accounting for the internal units of account of which is provided by a decentralized payment system (there is no internal or external administrator or any analogue thereof)[1][2], which operates in a fully automatic mode. Cryptocurrency itself does not have any or a special material or electronic form - it is simply a number indicating the amount of data of units of account, which is recorded in the corresponding position of the information package of the data transfer protocol and often is not even encrypted, like all other information about transactions between system addresses.

Decentralization does not mean giving up data. And there are no serious prerequisites for the fact that there is less data about users. Users are happy to upload all their information to the social network. And corporations successfully analyze it and sell it to advertisers. The transition will take place when when decentralized networks will become more convenient and attractive than classic ones. Bitcoin is several orders of magnitude simpler, faster and cheaper than SWIFT. YouTube is more interesting than TV. News on Twitter appears earlier than in the media. Convenience and trust are the main incentives, not the technology behind them. Decentralization is a complex mechanism. Other things being equal, a centralized database is faster and cheaper to develop than a blockchain. If corporations can maintain user trust in their platforms, then decentralization may remain unclaimed by a wide range of users. I'm more interested whether corporations will want to take care of users without competition from decentralized platforms. Would there be streaming services without online piracy?
