When bear market comes in crypto world, so many people in social network sites shout "hodl". They just shout "hodl" without any proper reasons. Will it be right in the future? Maybe it would be right after some time when bull market hits the top.
My answer, however, is "sell and do not hold, and buy again." The timing is the main point. Sell your coins when bear market starts, and buy again when it touches the deepest edge. You can increase your coins with this strategy. Then, you can earn much more money in bull market.
It is not easy for average people to know when to sell and when to buy.
That's why we should study economy, finance, and crypto charts especially for bitcoin.
