Cloud mining is a terrible idea. It's even more terrible after the halving because most of them won't be profitable, not that most were before. Most of them take your money and give you someone else's until they run out of fools.
all "cloud mining" that can't sign a block and can't give an ip address for a block mined are simply scam.
other like cex.io now change their business and act in the market as exchange!
there is any connection between hip cloud mining (all site that promise an easy ROI) and halving!
