You can only trust yourself. Maybe I'm paranoid, of course, but trusting other people is quite dangerous, and often this risk does not justify itself.
You are right that one should always follow own strategy instead of others' advice, but in addition to trusting yourself, you should also benefit from the experience of other experienced investors. I think we need to learn from those who have experience in the crypto currency market. Experienced investors have a good understanding of all aspects of the market. Indeed, we should not blindly trust anyone.
Doing your own analysis, market intelligence and your own research is the best strategy for any project. I think one should always remember that whatever the field whatever the platform, newbies can always learn a lot from the useful advice of experienced people.
