Seems like you are talking about ponzi site miner scam site on here since you are talking about upgrades which is usually you can found on ponzi scam sites.If they do give free money but you will still need to deposit for you to be able to withdraw your earnings which means you will really risk money and later on you will get scammed. I would really not engage on this kind of websites.
