I can only speak for my self and from my own experience mining in CryptoExplora
I invested in CryptoEXplora a few days ago and untill now I can't really complain. There have been ups and downs but it was due to a lot of factors, mining market status and similar. But for all this time mining I can surley say that cryptoexplora is legit company which will not take your money and disappear. I am aware of a lot of scams and ponzi on mining market and I feel I was lucky I invested in CryptoExplora cause I have a few contracts running and I am paid every day www.cryptoxplora.com good luck what ever you decide and do your own investigation before you invest.
