I am sure there are people making thousands per day with domaining - I am NOT one of them - but this doesn't make it impossible. Domaining is hard but the beauty of it is that it gets easier with time, experience, and many losses along the way.
I do believe people selling their tips are selling the shovels but it's a business model IF they were as successful as they claim.
The problem is that EVERY SINGLE DOMAIN is unique! unlike anything else - even in Real Estate, you can 100% duplicate two buildings, but you can never do that in domaining! Every Single Appraisal is Invalid in my opinion - a million dollar domain in my eyes might not be worth registering in yours - So basically, I believe domaining is relatively hard in the beginning and gets easier with time and experience, and yes, I do believe people are making thousands a day! In every industry there are leaders who are making that and more.
After-all, if you have the money, you WILL make thousands per day for sure !! BUT, what's left in your inventory unsold that ALSO cost you thousands is not in the equation here
