It all depends on your risk appetite.

Your ROI computation is based on current BTC difficulty and current price.

Both will fluctuate with time, so your 202 days can turn out to be considerably less or considerably more.

One thing I can be sure is that your contract will not turn unprofitable BEFORE your ROI is reached,
so you can be assured of at least getting back your capital investment.

After getting back your ROI, the contract will keep giving you daily payouts until it becomes unprofitable to do so.

The SHA-256 contract price keeps rising because everyone anticipates that the price of bitcoin will soar in the near future.

That's why Genesis and Hashflare SHA-256 contracts are sold out.

The advantage of Bitcoin.com Pool contracts is that you can switch between mining Bitcoin or Bitcoin Cash (BCC),
whichever is more profitable to do so.

If you intend to mine bitcoins yourself, the cheapest route is to buy a Bitmain Antminer S9
and operate it at home. Its hashrate is only 13.5 TH/s and consumes 1323W of electricity.

You can calculate the electricity cost of operating the S9, and compare it to the maintenance fees charged
by the cloud mining contract.

But all miners are sold out at Bitmain at the moment. You need to wait for them to release new stock.

Personally, I cannot stand the cooling fan noise of ASIC miners operating 24/7.

That's why I remote host my Antminers at GigaWatt in Washington State, USA.

Thanks for the suggestion.
