Investing in clouding mining is now a total waste of time.
It is a total waste of time because instead of investing your btc into trading and other legit profitable investments, you will have the chance to get scammed there.
The miner is the beneficiary here , who will charge for maintenance of rented rigs at your expense profit or no profit!
And sometimes there is no real mining rig and you are only seeing a fake stats that is being made by the scammer, so this is a very risky way of investing. Just trade guys and you will earn potential good profit.
