Both. buying decision during Q1 of 2022, was bad. cause market got down and still under bear attack. Although nobody knew that market can dump but buying crypto with that high price like $50-60k was bad idea. There's a Policy that, never buy crypto when that already pump too much and market will dump after pump! Whatever now Q4 of 2022, giving opportunity. Who brought crypto with their ath, can buy crypto and Average the loss. Thus loss will be covered but don't know how long need to wait.
Quarter 1 must be a time for selling. It's better to sell and take a little more than seeing your money gets shattered slowly but like you said no one expects this to happen. There's no way to tell if what can happen next. A lot of us are expecting that the fall on q1 is only lite but it will then recover later on so they refuse to sell.
There might be some kind of a policy on here but it was still up to the person. They still have the rights to do what they want and disobey any rules. We are now in quarter 4 and if there are any opportunities here, that will only be buying since the price is showing a signs of a decline and many of us claims that the bottom is near.
