How better an aged twitter account would be

I got a seller who got an old twitter account aroud 6 yrs old with very little activity.
Howmuch that could be the worth ?

How could i use to its full potential if I were to buy that account ?

Haven’t tested twitter limits in a while, they might have changed stuff so others can chime in with this. It will let you do some more actions but it’s not invulnerable, if you go over the limits it can still get banned. Also activity on the account is a factor, if the account was dormant and you start doing thousands of action daily it will certainly seem strange, you still need to take it easy. If it has no followers on it, i wouldn’t go more than 5 maybe $10 - unless it had an amazing name or something…
