Aside from here, where else?
I read about them, I search any where I can get information about them then I read everything about them to know much better on how they work. I can also make enquiries from those who have been investing in it to know what they think about it. Another thing is that Im not the type that usually get interested in new stuffs, I prefer old stuffs that has been around for long and has potential. As long as what I have is working for me and Im satisfied with it, then why look for something else?
