No pain, no gain. If you want to book your future profit with btc mining and don't have the essential hardware to mine btc then OXBTC is best choice for you. I am sure there are many people investing there money here because of lack of huge capital for mining.
No, if you do not have the money to buy mining equipment your best choice is to keep whatever amount of money that you are currently holding and then keep saving until you do and finally buy your own mining equipment, otherwise if you fall on this and you invest in one of those cloudmining sites you will get scammed, I know this is not what people want to hear about their investment possibilities but it is better to face the truth than to believe a lie.
