It sounds very easy to say buy "low" and sell "high" when trading. If it was the case, everyone would be doing this and everyone by now would be very rich. But that doesn't happen because you can't always execute your trades accurately. You might buy low, but the price might go even lower, so you should either cut your losses and continue what you are doing or hold your coins.
But it is easier to do this if you are willing to hold. Buy low, hold and sell when the price is high. Keep on repeating.
it is easier to invest than daily trading with short time frames. when we invest maybe we can apply buy low sell high, because if the price goes back down, then we can buy it again and hold it until we get a profit. but this will be safer for top coins, where even if there is a decline, later it will not be able to rise again, it is different for many new coins that are difficult to reach new ATH again, even many are abandoned by investors and eventually disappear from circulationBut it is easier to do this if you are willing to hold. Buy low, hold and sell when the price is high. Keep on repeating.
Buy low and Sell high might really that simple to hear up just like on what others been saying or even us would really be having that kind of impression but doing it honestly is the toughest thing to be achieved.
Just go on things which you do see that it would really be that effective for you to deal with specially with investment or trading.
