Yes I shall write down these sites on black list on the internet. There is many people on other forums advices me to hire a hacker? Perhaps this hacker take my money and do nothing, only cheat hacker. can someone recommend an honest hacker? 
There are white hackers but you will still have to spend money taking them down, they already made profit from scamming you 19 Bitcoin is such a large amount, where have you been all this time when people are posting that cloud minings are scam and it's a Ponzi scheme, I don't think you can get your money back, you can make a crusade to fight scam by sharing your lesson.
