All is about our perspective and point of view. Pessimistic people will think this is the end of crypto, we should sell and leave crypto.
But the Opportunistic people will always take any opportunity even in this bear market. They buy and accumulates during this phase, and patiently wait for crypto hype again in few years later.
In this case, there are 3 options for behavior in a bear market:
you buy coins at a reduced price;
you are fixing a loss;
you continue to hold coins, waiting for the price to recover.
And only the first option is preferable in a bear market, but it is only for those who have sold their coins at a high price in a timely manner.
The 1st and 3rd option suits better, buy and hodl while the market is red. Buy coins while we can still buy them at a discounted price but the challenge is to to find and invest in the right coins because not all coins or projects especially the newer ones will survive throughout the bear period. And then hold while the storm is still going on, project and set-up some timetable to be your guide in the future.
