I keep thinking that I should remove intial stake but at the moment I do not really need the money and so would likely reinvest into something else that might be more or equally speculative anyway - bad move perhaps. Also I have read lots about compound interest etc and this is too powerful a tool for me to subvert without a very good reason. Luckily I also have 2/3 of my money in equities which are less volatile and an independent asset class and should prevent penury in even apocalyptic times.
