You gotta consider: What changed? The platform, your understanding or your feeling?
If you invested in SteemPower, you knew it is long term commitment, therefore, there is no good in short term price fluctuations.

Did the reasons that made you invest in the first place fundamentally changed or just your opinion? This reflection could make you a huge difference in future investments.

It doesnt matter how much you had, what matters is how much you have now and if it is invested in something that you consider to have value.
