I purchased their service (v1.1) by sending them bitcoin as payment last 3 days. After 24hours I went back to the site only to find that the default free package wasn't upgraded and the website owner didn't even bother replying my email. After reading bad reviews about this site I know that I've been scammed. The owner sometimes reply in their bad review "hey, I got payment but I have to pay small fees". The fees itself is just another scam! If you ever stumble upon this site RUN FOR YOUR LIFE!
If you ever thinking about buying please search this keyword on Google first:
"99mining. Cloud scam or legit"
You'll tons of bad reviews from peoples who got scammed by this site. The identity of website owner is unclear, fake address used by many scammers.
