Conclusion

Every programming language has the potential to make you lots of money. You just need to join the top 20% of coders and you’ll make six figures easily.

However, some programming languages are inherently more attractive than others.

My secret tip is Solidity which is the programming language to use as a Blockchain engineer. This has hugely growing demand (I’ve never seen such a thing in programming) and many Blockchain engineers make $100 and up to $250 per hour!

Solidity Learn and Earn

The Finxter CS Academy has many Solidity courses in case you’re motivated to learn!

Where to Go From Here?

Enough theory. Let’s get some practice!

Coders get paid six figures and more because they can solve problems more effectively using machine intelligence and automation.

To become more successful in coding, solve more real problems for real people. That’s how you polish the skills you really need in practice. After all, what’s the use of learning theory that nobody ever needs?

You build high-value coding skills by working on practical coding projects!

Do you want to stop learning with toy projects and focus on practical code projects that earn you money and solve real problems for people?

🚀 If your answer is YES!, consider becoming a Python freelance developer! It’s the best way of approaching the task of improving your Python skills—even if you are a complete beginner.

If you just want to learn about the freelancing opportunity, feel free to watch my free webinar “How to Build Your High-Income Skill Python” and learn how I grew my coding business online and how you can, too—from the comfort of your own home.
