how to omega coin earn?

I'm sorry, but I'm not sure what you mean by "omega coin." There are many different cryptocurrencies in circulation, and some of them may be called "omega coin," but without more information, I can't provide a specific answer.

However, in general, there are several ways to earn cryptocurrency:

Mining: Some crypto currencies, like Bitcoin, can be "mined" by using powerful computers to solve complex mathematical problems. As a reward for contributing computing power, miners earn newly-minted coins.
Staking: Some cryptocurrencies, like Ethereum, use a proof-of-stake consensus mechanism, which means that users can "stake" their coins as collateral to help validate transactions on the network. In exchange for staking, users can earn rewards in the form of additional coins.
Trading: Cryptocurrencies can be bought and sold on exchanges, and traders can profit from fluctuations in the price of a given coin.
Airdrops: Some crypto currency projects will distribute free coins to users as a way of promoting their platform.
Affiliate programs: Some cryptocurrency exchanges and platforms offer affiliate  programs that allow users to earn commissions for referring new users to the platform.
