You should register a personal wallet if you do not have a business (and you are not an individual entrepreneur).

You should register as a business if you are an individual entrepreneur or if you have a business (e.g. a LTD, Inc, LP or any other) or you are a nonprofit organization (e.g. nonprofit LTD, foundation or trust). If you register as an organization, you must provide other data in addition to your email address and password (e.g. the precise name of the company, company registration number, registered seat).
