Can we expect Bitcoin and other types of coins to have good prices at the end of this year because 2018 will end. I'm starting to worry that next year will experience the same thing 
This topic I think worries a lot and she is already very tired. If you have disbelief in the cryptocurrency, then no one bothers you to leave the crypto market and do something else. I hope that in the end the market will remain a minority that believes in progress despite the attempts of many countries to ban cryptocurrency.
