Anything can happen, there is no surety that the 2019 year will be good for the crypto market. A lot of people are talking about positive things in 2019, but we don't know what will exactly happen. If the bear market continues throughout the 2019 year then the crypto market will face some big threats! New people will stop coming in this market and many crypto fans will leave this platform too! But I hope these all negative things will not happen in 2019 because it's already happened in this year!
