Not to confuse "White Label" with "SaaS" which means "As a Service" They are very similar︃ concepts but there are some small differences, for example, you can have a provider that︄ sells you a "White Label Exchange" "As a Service", but in some cases, we use︅ the term white label simply to refer to a solution that is ready to to︆ be used, just need you to put your brand (label) on it.
For example, in︇ the Binance case, yes the business is fully on their hand, but in other cases,︈ you may install the white label solution on your own server therefore having full control︉ of the customer base.
