I trust bitcoin because I trust maths.
Can you elaborate more on what you have said? I know bitcoin exist because of 1s and 0s, But its more than that to make you trust Bitcoin. Even though it has numbers on it, it does not make me trust something. For example I don't trust any mining site as they still don't have any proof of such a company exist. But I trust Bitcoin not only because of its price but also because of its acceptance from big businesses.
What I meant is that I trust the bitcoin structure, it is worth it. What I don't trust is the use some people are making out of it (scams and mining sites, as you said). I admit that there is still much work to do on bitcoin, much more to discover. I didn't mean that I trust the system that was built over btc completely.
