It's normal to trust bitcoin more than your bank I love your deep believe in bitcoin, on the other hands I we also advise you to listen to what your friend is telling you don't put all your energy investing in bitcoin but invest, invest what you know you can't afford to lose in bitcoin, the crypto market is unpredictable no matter the trust and believe we have for bitcoin we still invest with caution because anything can happen in the future, investing in bitcoin is good because it's a volatile asset with potentials and it's also risky, so my brother investment is good but invest with caution.
