You never believe articles published by a domain registrar pumping a domain extension. Why do you think they do that, they want you to register some .online names with them, thats their business. The best test is to email some shares, cannabis, real estate, insurance etc companies and ask them the following 1) Have they heard of the .online extension? 2) Are they interested in buying one? I can almost assure you the answer will be "no" Focus on extensions that sell, its the best way to make money in this business.
