I’m a native Texan with extensive travels over all the USA, Mexico, South America, Africa and Asia. I have been self-employed since 1997 in a variety of businesses including, C-stores, Restaurants, Real Estate, Agriculture and yes, Online Business.

Like you, I had seen all these ads on social media and YouTube with these 20 year old “kids” making all this money online, and figured if they could do it, surely I could do it with my extensive business background and experience.

And, guess what, I did. But, not without making a few costly mistakes along the way. Yes, I’ve been scammed before, and it ain’t fun. Now, after all these years in online business, and reviewing hundreds of courses, opportunities, gurus and platforms, I am able to sift out the BS from the legit opportunities.


I don’t like being scammed and the world of online business has more than it’s share of low quality courses, platforms and downright SCAMS. I want to help you avoid the mistakes I’ve made and help you create a real, long-term, profitable online business.

A business you can run from anywhere you get an internet connection. A business that keeps working for you even when your asleep or on vacation. A business that you can pass down to your kids or even sell for a big profit if you want.

If you’re like me, you’re probably skeptical of this whole online business thing and that is perfectly natural. Let me do the heavy lifting and research for you before you spend your hard-earned money on something that may not be legit.

If you come across a course, program or online opportunity that you’re unsure of, just leave it in the comments below and I’ll check into it for you. I’ll be your guinea pig so you don’t have to worry.


My Goal with this website is to help you navigate the sometimes “shady” world of online business and making money “dinero” online. I will be reviewing business opportunities, programs, platforms and courses to give you the heads up on what to expect and which ones are legit and which ones are Crap, or worse, just plain SCAMS.

I will also be showing you the tools and apps that you can use to accelerate your online business success. Tools that in most cases are free to use. I like FREE, I bet you do too. 😉 I will also be giving you tips, techniques and strategies to help you build your business for long-term profitability.

If you ever need a hand or have any questions, please feel free to leave them below and I will be more than happy to help you out. If you are uncomfortable leaving a public comment you can email to: rex@dotcomdinero.com and I’ll get back to you ASAP.

Wishing You Much Success,
