To some extent we can predict if bitcoin is going to recover before before December this year but I doubt if ethereum and some of it tokens will recover before December. Before December lasy year, when bitcoin is getting pump ethereum will also be getting pump but I see bitcoin going up now and ethereum is getting dumping.
Until December, will not return to the previous level, only if next year. There are still many shortcomings with him and I believe that you can safely find a replacement that will be much more dynamic and interesting.
