I unfortunately just recently started looking into BTC and ALT coins and while there is a ton of information here it is hard for me to discern good info from bad. It seems like a lot of the things people post are either ads or sarcastic comments to steer people away. Any tips on who to trust?
Yourself.
Yep, that's about it. I'd do some reading here if I were you, before you make any big decisions. There are definitely some knowledgeable people here, but there are some scoundrels as well--many of them. Take a look at some of the older threads from when bitcoin was just taking off and everyone here spoke English. There's some good stuff.
Also to reiterate: trust yourself, no one else.
