I don’t know why people do make it look like it’s only long term investors that do make profit from bitcoin investment, seriously that’s wrong, even short term investors are making profit from bitcoin investment, just that the risk involved in short term investment is really high, the chances of losing money is just kind of high, and they might not really be making much profit compare with people holding bitcoin for long term, but we shouldn’t just make people feel like if they are investing for short term, then they won’t really be making money from bitcoin investment, if they get things right, then they will be making money.
It's due to the belief Bitcoin profit can be made on short term that many investors end losing money, as they didn't prepare themselves to hold their coins for a long time, so they sell their coins at loss, because they can't wait anymore in order to pay a debt, daily expense or for an emergency. It's possible to make short term profit from BTC investment, but in every cases, the investor has to be prepared for the scenario where it's not possible, forcing him to hold for longer. It's a safety measure which shouldn't be neglected by investors, as it can save them from losing funds.
