Well, Cloud mining is very popular now when it comes to cryptocurrency world but we should be more knowledgeable in finding a legit cloud mining platform because other platform is not paying. Now I am still finding a legitimate cloud mining and I think the best cloud mining site is a btc online and eth online because it is legitimate that I only try. Its up to you if you want to upgrade or by referral in this two sites. For so many cloud mining site that two is the site that I have tried that it is legitimate.
