I have received 124 payouts now on my Dash contracts which seemed really profitable in the beginning. The contracts cost me 9.33 dash and the total payout I got so far is 5.39 dash. So I got little over half my money back in 4 months. Still have 20 months to go on this contract but the initial payout was 0.071 Dash and that has dropped to 0.019 about 27% of the first payout.
Let's assume that this trend continues, then my payout over the next 4 months will be 1.44 Dash, and then 0.38 Dash, 0.10 Dash, 0.028 and 0.0074 Dash. The total over 2 years will thus be about 7.35 Dash, a loss of about 2 Dash. Now some say you should re-invest, but logic dictates that you will also lose on that reinvestment, thus increasing your losses.

I used to be much more positive on GM but results and especially recent events have made me lose all confidence. These Dash contracts gave me little problems, I must admit, just a few small errors in the payouts. But then I opened a second account for my daughter and that was really nothing but trouble. In 30 mining days there were more than 10 errors, 7 of which were missing payouts that are still missing today. I wrote 'more than 10' because I am not counting the missing payouts since they say they have been hacked.
Which is something that I do not believe. This story is, in my opinion, a cover up for a more serious issue. If the were hacked they should not stop the payouts as our money is more safe with us than with them.
