I always use highly volatile coins and stable coins trading pairs. Sometimes it works well but sometimes, as normal I lose.
In uncertain times, price is usually boring and it does not change too much. It often fluctuates up and down with very small price change margin. It's not intersting time for trading because when you trade, you need volatility. However, if you are in uncertain time, you will now know that next big volatility will be up or down, and it's very risky to hold your position and hope that market will move up or down to give your position profit.
I will wait for the market to start its high volatility time, a big crash, then I wait for like 30 minutes or 1 hour, before I start trading. If you want a safer entry, you can wait like 4 hours after a crash to enter the market.
I would say that trading is just good and profitable during bull season but not during bear season.
Trading is for both market types, bear and bull. In bear and bull market, you always will see market crash, correction but if you can wait for it to happen, wait for a few hours for market to calm down, you can trade in both bear and bull market.
Trading means you don't let your position opens for a long time and you don't hold your position in days or weeks.
