There is no point in discussing about payment processors here because :

It's a scam. I lost my money with 365funds.com, thunderfunds.com, both have similar plans. Both sites pay only till you get back half of your investment, and then they stop paying.
I invested $7, they were sending me daily interest until I got back 3.3$, and then they stopped paying me. Thus I lost 3.70$ with them. They are doing the same with all members.
Similarly, thunderfunds.com, did the same, they stopped paying me after I got back my half of the investment.

I think it's better to change the title to "Best Scam HYIP - 365funds.com"
