Solidtrustpay.com. It's one of the main payment processors for HYIPs. I wouldn't trust it, its name sounds sarcastic 
Correct. HYIPs love Solidtrustpay, perfect money and bitcoin because they won't get banned for any money laundering cases like PayPal
Woah, never knew that. Really? I thought it was none-reversible, like PM.
I also thought it is nonreversible but one day I talked with them and they told that transaction can be reversed in few cases but not in all
Well, definitely stay away then. Reversible methods with newbies arent a good mix
