I have a big interest to enter the Fintech and blockchain industry.. But, I have a lot of afraid and questions . Plz Help me

Hi, hope you're doing well ! . I really need your help, I have a big interest to enter the Fintech industry .I have a lot of questions, but the most important question is " Does a Blockchain industry is good industry for future ".

If The blockchain is a pretty good industry, What problems could face anyone in this industry? I mean that I've read articles that said that the blockchain is the next internet generation and praised the industry a lot and others, but others said It's nothing , unstable and SALARIES DEPEND ON HOW HIGH ARE THE CRYPTOCURRENCIES AND THE DEMAND ON THEM, and it is just a phenomenon. How could you see that ? + Is that so right ?

So , I'm so afraid of all of these, and I really need your opinion as professional people , because I'm torn between entering this profession and avoiding it.

The sth that I'm so afraid, and I don't know how to make my decision for reasons I said before . So if you were me ?? What is ur opinion??? I really need ur advice

Thanks a lot in advance :D
