I think you might have got your answer with proof by now, Bitcoin cannot be dumped so easily. People are believing in Bitcoin and hence investing in it after seen that Bitcoin is definitely the investment of future. Hence they might hold until they get the required profit and it does not seem that all the newbie investors will sell at the same time, thereby no such conditions as dumping in Bitcoin. Moreover, it may push back to 9K USD but 7k USD is only possible in the worst possible situations or for a short interval correction.
