A mentor can accelerate your learning process, offer objective feedback, and help you navigate the emotional aspects of trading, ultimately increasing your chances of success.
It's not even a matter of "can accelerate", it "should accelerate" ought to be the expectation except the person referred to as a mentor is a mediocre. I've stood on the shoulders of a few I recognize as mentors and they propelled me faster than I thought, though not in cryptos. My crypto journey was haphazard, I couldn't find anyone to mentor me directly. I read most things starting up here and then grew wings to test the wind. Not having a mentor kind of slowed my moves, I've to admit.
