Trading can definitely be more profitable than simply holding bitcoin but just for traders with experience.
At this time where the coin prices are swinging it can be very tricky to catch the right moments to do the right decisions. You have to invest a lot of time in research if you choose this path. If you can't afford the time to do this: holding bitcoin for long term is also an alternative. You'll get a profit out of it either way

People who don't really understand Bitcoin are the ones who don't like it. Many don't want to accept that we're in the digital / crypto era and bitcoin fits perfectly in. It's something with an incredible power to change things and history shows that people are often afraid of innovation and changes. Some others simply don't like the fact that they are not part of the great bitcoin development and show hatred and jealousy. If someone doesn't want to understand Bitcoin or dislikes the idea of btc without even giving a reason why, just leave them alone. The future of crypto holders is bright and don't let other people put you down
