Even verified or legit cloud mining sites won't give you the best profit. And hardly, you will get the ROI of your money. This is why, even legends here are not advising to invest on a cloud mining site. Better buy your own equipment. At least, if you are not earning anymore from that equipment, you still have the hardware that you can use for other purposes or something to sell. But with cloud mining, once they stop paying you, hard to run after them. Your money is considered lost.
