it no so about the mining difficulty how is about the low price :)

Because of the increasing difficulty of mining, the time period for getting ROI increases severely. Sometime it could even increase so much that you will not even break even. This is why it better to either buy Asic or just purchase the bitcoins and Hodl until the price increases. Then you can buy the hashflare contract. since now you are buying double the amount of hash power compared to what you would buy initially with direct investment.
