Last 2 days I bought for about some cheap coins and it went down for about 5% or something and I decided to sell. And now, I am at full regret that all of those coins are now up for about 20%. My lesson for that is to be patient since the market was down for some day and it will always go back up.
It's strange that you initially saw that the market was falling and buying coins, in which the price fell, and this was the right decision. But why, when their price has diminished - have you sold it? The market has not yet fully recovered. It's good that you learned the lesson and shared it with others. Thank you.
