Okcoin is a cryptocurrency exchange where traders and merchants buy and sell digital currencies, we all know this already.
My first encounter with the Okcoin exchange was as a result of a STX airdrop program that is still currently featured on the exchange. I've never heard about this exchange until the airdrop program which attracted me, then I registered on the exchange.
To be a part of the airdrop program, you have to be a registered user of the Okcoin exchange, completed your verification whether for an individual account or a corporate account the option is there. And you can't create both, you can only create one of either a corporate account or an individual account.
Then, the main requirement to be eligible for the airdrop program is to trade STX on the Okcoin exchange platform which then gives one the opportunity to earn BTC in fractions.
Another way to earn on the Okcoin is through Stacking STX. To stack, you deposit and lock your STX on the exchange for a while to support the security of the network and you receive BTC as a reward for so doing. Stacking almost looks like staking don't you think? Or maybe it's just English word differentiates them. Now, the reward one earns from stacking comes from the BTC that miners transfer as a proof of transfer. Which is like a thank you gift for contributing to the security of the platform.
Should Incase you don't really understand the process I described above you can visit the Okcoin exchange platform and check the FAQ section, there you will get a better understanding.
