I really don't know what I should say! Although my friend made a lot of profit with a mining contract some months ago the newer ones just doesn't seem to pay off for me... at least in the bitcoin world!
First companies like https://genesis-mining.com start offering scrypt mining contracts. It could be an opportunity like hashpower contracts  were a big success in the earlier days of sha mining.
They also seem to have a clever innovation to mine the most profitable altcoins to pay out in bitcoin. According to their FAQ this should be a much more profitable way than to mine bitcoin directly.

It could be interesting if you look at their prices, but its still a risk looking at the scrypt total  hashrate!
