College education and certifications don't help too much these days. This was valid 20-30 years ago but not anymore. You can learn a lot online for free. Investing in BTC might be good in the long run. Nobody can give you an exact answer. Only you can decide what's best for you. Good luck!
That's true. Every time I went to look for work they briefly took a glance at the papers and proceeded with the interview. Usually your certificates mean shit, so they will decide if they should take you based on whether:
1. You're connected. If your friend works there or they know your parents you often have the job before the interview starts.
2. You have experience, which is the most important thing
3. If you have no experience, if you know what you're talking about.
Then if they still can't decide because there are 2 people for the same job and you both are equals in all other aspects, they'll look at certificates and stuff but usually being from the same town as the interviewer will have a greater value than the courses you did.
