Currently im investing all of my coins into the project i do wanna to put online, but next year i do hope to stop invest and start saving, on the last halving i take a lesson, that were if i had saved my coins i could had found already my project instead had invested them.
I will not hold you to invest because it will be good anyway because your bitcoin grow but it is better if you do not invest all coinmu, it might be better if you use half of it
