What’s the difference between fresher and aged accounts ?

The fresher the account, the more it is sensible to actions in the first days of use, and more likely to ask for phone verification at login or after a few actions. The more aged, the more it can endure. However, while aged accounts can easily accept login from other locations and resist at more daily actions, it is safer to warm up any account regardless of age, like proceeding with only a few actions daily, for a few days. If fresh accounts are warmed up properly, in time they can be as much as effective as aged accounts.
