Selling my Twitter account that I grew from 0 followers myself.
This account gets over 40k impressions per tweet. You can't base the activity off of the RTs and Favs since it's a babe niche and most people don't really RT those tweets or fav them. But I can show proof of impressions, engagements, etc.
Organic impressions:
Another thing that makes this account 3x as valuable is that it has access to Twitter's private verification page. Meaning you can submit any account you want for verification. I've successfully verified 3-4 people already and got paid $1k+ for each. (keep in mind these were celebrities/public figures).
It's currently growing by itself without a deck at a pace of 600-1000 followers daily.
I am in no rush to sell this. So unless I get a good offer, I'll most likely keep it.
