Is a cloud mining subscription worth it? I just started investing in Bitcoin and before I actually implement it, I want to verify my strategy / steps. 

1) I made a wallet account on blockchain. 
2) I want to purchase subscription from Genesis Mining for 1TH/s at $150. 

My aim is to run this for a few months and transfer bitcoins to my wallet and see how market behaves. 

Is this a good option for beginners to invest or get an idea of how Bitcoin  works?
Keep in mind, at current prices it would take a very long time to get your initial investment back with cloud mining. There have been many reports of cloud mining to be a ponzi pyramid scheme as they have the advantage of "time" on their side. They are basically paying you back what you paid them slowly.

However, if the price of BTC does rise significantly you can make a profit doing cloud mining. You are better off using the $150 to buy $150 worth of btc and holding that vs mining it via the cloud. You would instantly get the BTC to USD value vs waiting.

My advice if you want to get into mining as a "hobby" just get a usb miner you can find on ebay. Or just mine with your computer and join a pool with one of the other profitable coins found here: http://www.coinwarz.com -- bitcoin mining is a losing battle for the soloist.
