What you mean on most trusted? Or you mean profitable? If you are looking for both I think Nano is one of the best option right now. Its the 1 most profitable alts since last year and the dev working hard making it more trust worthy
Again, I think this is a matter of how you define "trustworthy"...just being a solid coin might not be enough to gain trust, there have to be other factors in it.
You might be right that its not really enough to trust some coin with just being solid coin but Bitcoin is also not in that criteria since we don't really know the faces behind it.
