now it's going down and tomorrow we don't know what will happen, so to make an investment it all depends on your belief, if you feel it has gone down enough then buy it but if you feel it will still go down then wait for the right time
Buying must also be with confidence so that some people prefer to place buy orders at a lower price when they believe that a decline will still occur, but the opposite is also possible so that those who buy at market prices can immediately get a profit when the price starts to increase and no longer declining in the market.
