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!
I need to disagree, it depends with your dream job or what skill you're want to learn.
Lets say you're want to become a doctor with specialist, yes you can learn from online and you've mastered many courses, but is there any patient who trust you can cure him when you have nothing to prove if you're a doctor?
Investing in BTC for long term is good, but if he only know how to grow his wealth and he doesn't have any money, how he can buy Bitcoin?
