Just update your public bio to set btc attractive lines and attract btcians by following a btc thread. Simple!
That's right. That's what I did... I update my bio. I've created my twitter account in August 2017 last year solely for the purpose of joining twitter bounty on this forum. Now, I have 5,325 followers and still counting. Aside from the bio, I think it's good also to be active every day by tweeting and/or retweeting others post.
