Invest when you already sets all the plans, it's tough to rush when you see unexpected fall, you'll be temp to sell with losses.
investment must always be ready for unexpected increases or decreases, by being patient and not panicking quickly, everything can go well without experiencing losses.
If you are planning to invest at this rate then when the market reverses they will sell off at a loss and the main point they need to understand is that if they are willing to take risk then they need to be willing to hold for a much longer time if the market reverses rather than selling off at a loss and if that is the mindset then they can invest at any market rate.
Analysis is very important before determining whether we are going to invest, if we are sure it takes patience and not panic, because the decline and increase that occurs will always occur, it's just how we can manage to stay afloat so as not to lose because we believe that there will be an increase in the future. so if you are sure, then you will hold as long as possible until what we want happens.
