Bottom line, in terms of USD, its like a savings account but in terms of BTC, its a loss making investment. if you wait long enough, I suppose you could get your money back but by my counting, it could be 2 years. I'm here referring to the Bitcoin open ended mining on Genesis mining. I ordered a 0.5TH mining contract for Bitcoin on 1st June 2016 for $94.88 or 0.18BTC at the time. Today, the payout has been $322 but only 0.11BTC.
Here is my take on it;
Buy and hold is better than investing your BTC in a contract. If I never spent that 0.18BTC then, I would have had $486 today.
