When there is panicking in the market, I just continue holding or convert to USDT stable coin and watch the market, with expectation on a good reversal to jump in again. At this point, with this technic, I secure the initial price of my asset, Bitcoin mostly, and when it starts recovering from its deep, I buy and secure more profit as it goes up. While on the other hand, when the market is on a deep, I buy more of the deep, while it last for the period it will.
When the market is filled with panicking, either selling/buying the market shows reactions, and as a trader, buying the deep is the very sure thing to do, and selling at the top for profit take out when the up trend volatility shows.
