Here are the bitcoin charts from the last two bubbles 2013/2014 and 2017/2018. They look very similar and if history repeats we may expect long downtrend for at least one more year.

The cycles repeat very similarly, just 2013 it took more time. Do you think the same will happen?
Do you thing the altcoins will follow different pattern, if they release good working products. Isn't it better to switch to utility coins like Etherium, EOS, NEO, Cardano, IOTA, ICON and similar projects?
