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.
It is most likely that bitcoin, as in all previous years, will also rise in price in the last months of the year. This time we expect almost a year. Following bitcoin, ethereum and the rest of the crypto currency will necessarily rise. Ethereum should grow this year, it has fallen very much now in price and is a very underrated coin.
