Many people made much money and other loss much from invest. Im not sure if your question have correct answer.
Still all who invested in cloudminr.io hope for profit and earn. They offer good ratio contract price/pay outs compare some BIG names. Problem is any company can fail and make his investors loss. Good example is BANKS from real life. So never invest what you cant afford to loss!
