title: Will Heroku's Account Verification charge any value?
body: <p>I have a personal blog hosted in Heroku. I want to buy a custom domain name and point it to my Heroku's app.</p>
  
  <p>Heroku requires a credit card to add custom domains. It's called "Account Verification".</p>
  
  <p>Right now I don't want/can't afford any value from a hosting company. I want to use Heroku completely free.</p>
  
  <p>Will Heroku's Account Verification charge any value?</p>
  
  <p>If my app get too much access, will it scale automatically and charge for it?</p>
