Welcome to NPs @saiyathra ! And that reply that @Kenny gave has some great resources for getting started. I think the secret is truly listening to advice from seasoned, experienced people here, especially when they give evidence for what they say, but don't let that reduce your confidence in the insights, and unique expertise that you bring to domain investing! Fresh ideas make us all stronger!
Just like to second what @Ategy.com just posted - why not tell us how your interest in domain name investing started, and what sort of niches do you see being active in. Best of luck!
