You noticed a crypto that has gone down and you think it will go up again. So you buy it and, as luck would have it, at the moment you bought it, it starts to go down even more. If you had bought it later, not only would you not have lost money, but you would have also benefited from this continued decline.
What happened is that you bought at the wrong time. And this happens nine times out of ten. So what should you do?
When you spot a crypto that you think will go up, do not buy it. Add it to your favorites. Display the 1-hour price and come back regularly to see the best time to buy it. Use indicators (especially Bollinger Bands and RSI).
The more cryptos you have added to your favorites, the more buying opportunities you will have. And when the crypto has exhausted all its potential, remove it from your favorites and go back to fishing for favorites. It is a rather interesting game and will give you more chances to win money.
