Why can't I send bitcoins and ethers?

In order to send bitcoins or ethers, please set up SMS or Authentication App as your Two Factor Authentication Tool.

If you use SMS as your Two Factor Authentication, you will have a 20 SMS daily limit. When your SMS reached the daily limit, you will not be able to change your Two Factor Authentication or send digital assets.

Please note, for users who need to send large quantity of bitcoins and ethers, use Google Authentication or Authy as the Two Factor Authentication, which give no daily limit.
