Perhaps, I may have to change my cashing out formula because the formula allows for my selling about 1% for every 10% price rise, so for example, if I start out with $100, and the price shoots up 10x, then I have cashed out about the equivalent of my original investment of $100 but I still have about 9x of the principle which is $900. The same thing is true for the next 10x and the next 10x, so if anyone follows such a formula, then he would not run out of BTC to sell in the event that the price continues to increase by 10x, yet he will have accumulated a lot of fiat, to decide whether to keep it for reinvesting (because I don't think that we ever go up a straight 10x without some kind of price correction in there) or to cash some or all of that fiat out.
