I think all these questions asked here are directed at altcoins, not at Bitcoin because Bitcoin has proven itself to be an investment that is preferable. You will feel relaxed on to expect profits in the long run whether its price at decline, it will bounce back. You can't said that for all altcoins(bounce back). That's why questions like these need to asked on altcoins before investing. So that you will know the future of the coin whether it is bound to failure or success in short term.
