I think OpenANX is a legitimate project, so you should be safe. I used to order their Bitcoin visa card before and it works very well as for the OpenANX project, I think it's a great long-term investment and the project is still undervalued so it still has a lot of room to grow.
Thanks for your opinion about the project. How long do you think it will take for me to earn a good profit from it? I was thinking for a short-term basis, maybe just 2 weeks up to a month. But, as you have said their project is legitimate and still more room to grow so I'm kinda changing my mind for a bit here.
