Hold of course. I have never sold any assets of mine in bear market. However, there is a change to sell and then buy from dip if you follow the market well.
As for HIVE, it is a long-term investment for me, does not matter if it falls %50 tomorrow. Also, I think that we can recieve more HIVE from author and curation rewards in bull market.
Sell and buy the dip or, stake and continually buy the dip with smaller amounts? There are more decisions to make now. I think perhaps a hybrid approach for me.
I would prefer stake and buy dip.
