Hi Mg,
I started the same journey as you on December 9 ! I just noticed your post now.
I shall say i ve got the same fears and questions that you had when you started an that you may still have :
It is a scam ? is it a Ponzi ? What if they shut down on tomorrow, what if they are hacked and so one ....
As you reported already, hashflare is/was the only one to sell sha256 mining contracts ( and so far the most profitable ones ).
Unfortunately they are less communicating/transparent than Genesis for instance.
I choose to move from trading ( time consuming & addictive
) to mining since the BTC raise renders BTC mining profitable in a pretty short period of time.
I started with 83TH ( about 13 K$ or 0.74 BTC with the gains i made buying a few BTCs on last september )
No bad surprise till now.
I received my daily payout as expected, and i did my first withdrawal on yesterday ( it took as long as 16 hours to complete, because of the very low fee used by HF )
My purpose will be reach the break even in 84 days ( 0.01 daily payout at least ) reinvesting any remaining .BTCs to counterbalance the inevitable difficulty raise
Lets see !
