To keep up with the adventures of the Keswani family, visit PEOPLE.com/keswanis.

If you weren’t already familiar with the stellar Vine work of "Big Nik" Keswani, you’ve at least heard a lot about him this week on PEOPLE.com. And if there’s one thing you take away from his videos, he’d like it to be this:

“I don’t make bad Vines.”

The 17-year-old told PEOPLE at Stream Con in New York City on Friday that he first realized he’d made it “when one of my posts [#homealone] jumped from 100 likes to 10,000 likes.” And the rest is history.

But that’s not all there is to Nik, who was born with a rare form of dwarfism. He’s preparing to head off to college in the next year, and he’s fiercely protective of his younger sisters Sarina, 15, and Devina, 6, who recently transitioned from male to female.

“A lot of people think being transgender is a trend it’s more than that,” Nik explained, recalling the moment when Devina, then Dev, told the family she wanted to be a girl. “A 6-year-old asking for another life is a big sign,” he added. “We really accept her.”
