To hold the best for the time now, choose ETH, because this coin is quite potential, maybe only in a short time this coin up to 1000 $. And that is the opportunity for us to sell and take profit
Holding ETH for a long time is my top priority as I am sure the $1000 price will happen again and things will become more stable if the market enters the uptrend. What you need to do now is hope for a new future for Cryptocurrency as it is about to happen again in 2019.
