Actually for me regret in Crypto is just a moment, because if I keep thinking about regret then I will never step like this, indeed defeat will certainly continue in this Crypto, but should be used as a lesson for the future.
After all, later that regret will be replaced by something so extraordinary, like suddenly getting an unexpected profit. What we need to do is, do not respond that regret too deeply. All of them have their respective times, the important thing is not to despair in that matter.
