Let’s see the predictions for hashflare from November onwards (http://www.cloudmininganalysis.com/2017/11/25/hashflare-predictions-since-november-2017-for-btc-contracts/) . For the calculations we will make some assumptions regarding the last 6 months of BTC:
Difficulty increase of 6.294285714% every 2 weeks
Increase in BTC price of $ 399.0714286 every 2 weeks

For the example we will use this contract:
Duration: 1 year.
Hashrate: 24,200 GH/s.
Daily maintenance fee: $ 0.00035 / GHs = $ 8.47.
Price: $ 3,630.

Break even

Should we contract it today, the investment would be recovered in 4 months.

Until the end of the contract

The contract would last 1 year, having been mined 0.6360 BTC, which, to that date, the equivalent would be $11,257.0030 , or what means the same, a ROI of 310.1102%.

Mining BTC vs BTC direct purchase

If we buy $3,2630 in BTC (1 BTC = $ 8,630), we would buy 0.42062572 BTC.

Regarding the mining contract, it would be 0.63607101 BTC in 2019. We would obtain 51% more BTC.
