 Keep in mind that you cannot specify a difficulty and a vanity prefix at the same time.
 Also, the more requirements you have, the longer it will take to reach a satisfactory public key.
 
 ### Searching for multiple vanity targets at once
 
-Specifying multiple `vanity-n` targets allows you to leverage the work you've already done to generate each new `npub` candidate. Searching a candidate `npub` for additional targets is incredibly fast because it's just a trivial string compare.

 Statistically speaking, searching for `rana,h0dl` should take half the time that searching for `rana` and then doing a second, separate search for `hodl` would take.
