cloud mining investment is now just a shit thing as they down their servers and you wont be able to ROI , they only have excuses which no body wants to hear as every one want ton make some profit but if is not possible these days.
I think you just need to be careful about which cloud mining site you use. There are certain ones that have been around, have better prices and have good customer support. For instance lunamine in my sig is pretty new but they are so responsive and have been very honest in the sig campaign dealings.
