I think the major benefit from the Chinese bitcoin crackdown is their diminished control of the network, it was heading to the direction that they could possibly have started to perform a 51% attack on the network with the amount of hardware they were building up. It'll also be much better for the environment now all the dirty energy sources have less profitable ways to sell their energy supply - although maybe the real reason was them needing that energy supply for different manufacturing projects. Either way the price has stayed around the same since the announcement they are effectively banning Bitcoin so it is a small victory.
