Obviously, it is not going to be that easy to make a profit from this type of stuff, its easy to mistake the current situation and failure of most strategies as problems of the strategies, but the reality is that we shouldn't be making assumptions of any strategies during a bear period.
During bear season, better to save money and if you have decent amount spare then keep on buying with the assets that you believe that will bounce back and possible to reached a new ATH.
Things that could make you super rich during the bull run, could very well easily fail during the bear run and that is normal because it is the bear run and that is what you get during bear periods, losses.
The very reason to be wise not to be aggressive, observe and assess as the market may go further and keep falling.
So do not be hopeless about it, just stick to it and I am sure it will make you money when the bull comes, if it fails even at that point, then you can change it.
Adjust and not to dwell much if you fail with your attempt, learn from it and try to cope up with a better strategy, but be wise and not to be aggressive.
