If I can serve as an inspiration for you guys, I just got a job offer a few hours ago at 110k plus 20K tokens.
So, this is only a few weeks away, guys, like literally just a few weeks away. Hard work and you get there, like, immediately.
That’s crazy, you know. 130k USD in Thailand. I’m balling like this is gonna be a great time.
I joined Metana back in February 2023 to level up my Blockchain skills, I had some basic knowledge of Solidity + proficient in Javascript, but after putting in around 20 hours a week for 3-4 months(you may require discipline), I’ve gained a ton of skills. Plus, I’ve had the chance to meet some amazing people, like the Metana team and the other students. In fact, I’m even working on projects with one of the Metana students right now.
Metana brings you all the structure and resources to be able to go from beginner/medium to advanced regarding Solidity and Blockchain. I also got a job for DevRel in web3 even before finishing Metana bootcamp.

I’m currently enrolled in the Metana bootcamp. So far, it’s been a very pleasurable experience. I would definitely recommend this course for people who might have some basic knowledge of Solidity or programming in general since the learning curve is quite steep and there’s a lot of information packed into the different modules.
The mentors are very knowledgeable about their subjects and can give you in-depth guidance about specific questions you have. These are the kinds of things I’ve experienced, so I would definitely join up if you want to become a Solidity expert and learn everything from security to the implementation of smart contracts.
