OKEx is a cryptocurrency exchange that was founded in 2017 and is headquartered in Malta. It offers trading in a wide range of cryptocurrencies, including Bitcoin, Ethereum, Litecoin, and many others. OKEx also offers trading in futures and options contracts, as well as margin trading.

One of the notable features of OKEx is its security, which includes multi-factor authentication, cold storage for funds, and regular security audits. OKEx also offers a user-friendly interface, a mobile app, and 24/7 customer support.

OKEx has faced some controversies in the past, including an incident in 2020 where the founder was reportedly arrested by Chinese authorities. However, the exchange has continued to operate and has expanded its services to include more cryptocurrencies and trading options.

As with any cryptocurrency exchange, it is important to do your own research and understand the risks involved before trading on OKEx or any other platform.

OKX supports staking of several cryptocurrencies, including EOS, IOST, VSYS, ATOM, YOU, CRO, XTZ, and DAI. Staking is the process of locking your crypto assets to support the related blockchain networks and earn staking rewards from new assets generated on the blockchains, as well as transaction fees. OKX Pool has officially launched the beta staking service, which encourages users' long-term holding and offers rewards when the staking period expires. The estimated annual percentage yield (APY) for staking EOS at OKX can be up to 5.12%.
