Hello, @emon19. On Steemit, we value users' identity as such you are expected to have fulfilled a few requirements before you can be eligible to participate in our contests.

One of those things is getting verified in the Newcomers' Community and performing other achievement tasks over there. You can learn more about what is required of you in the newcomers' community through this link. Going through your profile, I realized you have been labelled for some forms of plagiarism at the Newcomers' community, you may need to redeem yourself over there and abide with the rules of the platform.

In addition, subscribe to other communities and publish your content, we would measure the legitimacy of your activities over time and you'd be qualified to participate here. At the moment, you are not eligible.
