Hey Kiran, welcome to Steemit!
That actually sounds like a great idea. I don't think there's any reason why we couldn't do a trustless gift-card system, with a private key for a redeemable amount of Steem. It might take some time to get support for it, just keep mentioning it. You could also propose it over on the GitHub project.
Thanks for your support. I'm a little new to blogging, so still getting used to it! That's a really good point, I'll give the Steem GitHub project a shot.
