I have seen this behavior even with services that haven't anything to do with crypto at all -- it has never resulted in anything of positive nature. It's a sign that sooner or later the chances are on the higher side that they will either close their service and run with people's funds, or they will look to shut down in the way of going bankrupt in the hope they walk out in a legal way. If people don't take this as a major red flag, they are 100% delusional -- cloud mining in general is already a rigged market, but some services just stink. People should withdraw their funds whenever they reach the minimum requirements. Don't reinvest, and don't leave any funds on there.
Everyone should learn on this act of hashflare.io, that's something very suspicious and they are trying to kill those small investors as if those people are hoping to earn with their small investments. There's too much defense and good words from their investors before here and I'm just speculating about cloud mining questions before and it's the other one that has been preferred by majority here next to genesis mining. While it's early, get out of the mess that they are about to do.
