Having recently received a reasonable fraction of a bitcoin, I am interested in what the optimal ways to cash out on it from a theoretical perspective are. Say I have some guess as to what chance it will have X value in Y years and have some quantified percentages of risk/security. How much do I sell now, how much should I hold on to "in case", etc? I feel like there is some mathematical advice here that I don't know. I feel like the best strategy should be something like "sell 50% every year" where 50% will be dependent on what I expect future performance to be. Edit: and ironically, it's the inconvenience of selling it that has kept me from doing so yet! The opposite of the author's problem.
