Being overly optimistic about investing can cause problems for an investor later. For example, if a person is optimistic after investing that his investment will make $4 or $5 profit immediately after investing or if he thinks that his investment will never go down. If someone thinks like this, he will be forced to sell his investment later. Because when he sees a decline in the market, he will get scared and then he may decide to sell his investment..
This may be possible, because if someone invests $200, there may be a profit of $4-5 in a short period of time. Now if you expect to make such a quick profit you will not be a successful investor. If you expect profit soon after investing then it is not wrong to call you a trader, to be an investor you have to buy bitcoins and hold on for long term. Now it is normal for the market to fall, so don't despair here. If one is disappointed to see the market down, he will not be able to hold for a long time, and if he cannot hold for a long time, he will not be a successful investor.
Some people are very funny, imagine investing $200 and then getting $4-5 in a short period as profit, this doesn't make any sense because if someone can afford to invest $200 then what is $4 or $5 profit? This explains lack of understanding because how will someone risk $200 just to make this little profit and this set of investor always sells their investment when the price is going against their wish. Long time is always the key to every successful investment and is not like some Investors don't know or understand but they decide to go the wrong direction.
