The network Ethereum employs more than 300 thousand developers, and since May to them, another 50 thousand programmers join each month.  The reason for this activity is in the high profitability of dApp.
 One of the decisive factors that contributed to the growth of cryptology last year was that Ethereum attracted a lot of developers ready to deal with dApp.  Now you can release new tokens on the block of coins or create a completely new kind of financial services, using the technology of intellectual contracts.  So Eth can become the engine of a new stage of growth of cryptology - first of all, because of the high activity of developers of decentralized applications (dApp).
