This exactly strategy made this coin as it is today............
For me this coin neads real miners and not nicehach,so it can be profitable for them and only then can catch the eyes of some one to invest on it.
The problem that pushes the difficulty so high is nicehash bots mining at a profit when the difficulty gets too low. The solution to stop them is to under cut them by buying nicehash mining at a lower profit and therefore being less disruptive to the block times. That is the only way to stop them from disrupting the blockchain because it effectively gets rid of their financial incentive to create the disruption.
