Your expectations were too high, that's all. Apparently you thought that there will always be a green color , but it turned out that there are red days, that vitamin D fell in your blood and you felt apathy.
the market often changes so that market movements often occur up and down. joining is no wrong time if you can manage your strategy well, try your best to follow it so you can get good results. if at this time you want to buy or invest just do it, because the market will improve and in my opinion this good time in the future will produce good.
