I wake up this morning and when I tried to refresh my wallet, I findout that bitcoin has lose over $700 from it high of yesterday! Immediately, "this thought come into my mind, don't be afraid, it is taking profits time", new confident come into my mind and I developed another hope that bitcoin is far strong now, better and menture now than in 2017. I will like to encourage us to keep holding and buying more at this time as bitcoin is on the way to the moon! Though, "this is not a recommendations for you to make investments decision"!
Here's what I gotta do, I'll keep on holding until such time the price is right. My definition of right price is that the price reach a peak price for a particular time. Take advantage of every peak price. Sell when you can profit. We know that the price goes up and down. So when the price is decreasing, buy some and if the price is increasing, sell some.
That is just the common strategy that's been used in most traders and it is a little bit risky if they plan the long-term investment but if it's riskier if they do short-term since the volatility of the market is quite strong. Though OP is right that it takes courage to take a profit in this kind of job.
