buy hashing power from CEX:IO and sell it when you're done with it. $200K will buy you just over 45THS. At that rate you would make over $1500 a day and probably about $40K a month. Take half of that $40K you make a month and purchase more mining power each month, which would be an additional 4THS per month at the current cost per GHS. After 6 months you would me around 70THS, and making $2300 a day or somewhere around $60K-70K a month.

In a year you would probably make your money back and then some. Once you're done, sell your hashing power back to the exchange for whatever the going rate is. Currently it's about $4.30 per GHS. In a year it might be back up when BTC has gone back up in value. So in theory you would make a profit selling your hashing power after making fat stacks of cash in the cloud mining realm.
