Software Engineer At Germany From India (Chancenkarte)

Hey People, I had this career option in my mind but not sure what to choose in between, So need some expert advices.

So basically, I am a Software Engineer in a well known MNC, Got placed from college with a package of 4LPA , And after 3 years today, I am still working on thr package of 4.5LPA, LOL Frustrating Right ? Although received review and ratings 2 times and promotion once , and in that promotion just got raised from 4 to 4.5.

This all makes me think of working no more in india, Since there is no value of your efforts and talent. TBH, I have worked day and nights for the company yet this are the results.

Now, After all this coming tovmy main concern, So basically recently I was searching around google to work in a foreign country based on Work Visa instead of going there as a student. Now since, I even have professional experience of 3Y. So ,I somehow landed to this germany Chancenkaet Visa , also known as Opportunity Card , Which allows working professional from India to enter germany and find a job, Now I need help from you all experts if anyone who is already experienced in this ? And how worth this is ? Is it preffered ? How Is Life There ? Ofcourse I have no relative there, But I am planning to step out of comfort to make my carrer better atleast. I am 24Y M. Thanks In Advanced For The Answers And Suggestions.
