For me its better to buy and hold your it, because after hard fork end the price are expected to be more expensive, so in that way you can make a huge profit by just buying and holding.
Good luck.
This is the personnal and individual decisions of every coin holders and investors to sell or hold their tokens , if they see that even if the price value of coins is down and they intendct sell their coins ,even if it is at risk then go, but if they think that the value of their coin will deficit if they will sell, then think of holding it until the time of the market rise.
