OKCash started as a mining POW currency, when 36,297,000 OKCash was initially mined (November 24 - December 9, 2014). Then he switched to POS. Every year, a certain percentage of coins is released and it decreases (69%, 20%, 10%, .... a total of 11 rounds of division - there are then multi-year cycles). Everything should be released around 2148. This is described in detail at https://okcashtalk.org/index.php/topic,16.0.html. OKCash has a large base and people from more than 40 countries are collaborating on its development. The platform is decentralized and changes to the code must be approved by the majority of the community. The platform and the coin work reliably without any problems at all times and the advantage is also a great name of the coin, which is understandable in most languages. Blocks are created after 72 seconds, so transaction confirmation is relatively fast. Fees are minimal (0.0001 OKCash - in some wallets you can set a higher fee = even faster confirmation in the network). Transactions are considered valid after 10 confirmations in the network. OKCash also works for IoT (Internet of Things) - currently for Raspberry Pi and Pine64 devices.
