I wouldn't call genesis-mining a scam, but it IS a clever way to make money from the mathematically challenged. The classic mining contract "scam" works as follows:
- Say at current difficulty, each unit of mining power would net you $50
- Sell 12 months of mining power at a price of $300
- Let the user come to the conclusion that they are getting $50 x 12 = $600 worth of mining at $300. What a great DEAL
- Neglect to mention that mining difficulty increases and price may wildly fluctuate, and that the 12 months of mining power is likely to be worth only $150 at the end
- Profit
I agree, many people definitely neglect mining difficulty increases.

Genesis mining in my opinion is better than mining by yourself. Eliminate the hassle for mining, maintenance cost. Doing the math concluded me it wasn't not much difference than doing it on genesis mining to actual mining. Given in reality that diffulty grows up inevitably and that one part of the risk and that is the problem that real actual miner encounter with mining.
However, my mind is in the long run. In the long run, it is profitable for me to do the mine in their company. Speculating the crypto will go up in value. If it is not then I admit it was a loss for a meantime.

Here's the maths for Genesis Mining . It may be a couple of week old but that doesn't invalidate the point.
Basically, at 2500 USD/BTC. Genesis Mining would have cost 0.78 BTC for 15 Th/s. With a 5% difficulty increase each round, you'd only mine 0.3539 BTC before the contract became unprofitable (you would have to pay GM money to keep the contract rather than make any money from it). That's a mere 45% of the cost of the contract after about 310 days of mining.
Obviously, if you just bought BTC you would have had 0.78 BTC instead of 0.3539 BTC. At 2500 USD/BTC, 0.78 BTC = 1950 and 0.3539 BTC = 885 USD. AT 3800 BTC/USD, 0.78 BTC = 2964 USD and 0.3539 BTC = 1344.82. The fact that BTC price has increased is irrelevant, you still have twice as much BTC and it would stil lbe worth twice as much USD.
You're right that cloud mining can be less costly than mining yourself for some people but if that's the case you shouldn't be mining at all for financial rewards as you're just going to loses money. Some people do it anyway for other reason such as helping to decentralise the network. Those reasons don't apply to cloud mining though.
The only way to earn money from cloud mining is through affiliate links which means you're ripping other people off to make up for your loss. In other words by scamming other people.
