Actually, that is a nice link infofront. The investment and cashing out strategy looks to be fairly similar to mine - except for that strategy seems to cash out 10% for every 100% price rise. My above example uses a similar proportion of cashing out 5% for every 50% price rise. Further, if you know that
in late 2013 Rpietila had a BTCtalk thread on the topic too, and Rpietila was suggesting to cash out 10% for every 100% price rise.
In about 2014/2015 I constructed a similar strategy to rpietila; however, I did not want to wait for BTC prices to double before cashing out 10%, so I played around with much smaller variations that are similar in their proportions, and I tend to play around with cashing out 1% for every 10% rise in price and I even play in smaller increments, too while keeping the cashing out proportions approximately the same or sometimes playing around a bit with the proportions if I am in more of a gambling mood. I believe that there were periods of time that I was cashing out higher proportions of BTC because I already realized that there was a pretty damned high likelihood that I would be using all or part of the cashed out money to buy back in, so I did not mind cashing out a bit more in order to attempt to more or less maintain a 10/1 ratio by accounting for my anticipated buying back.
It is true that some peeps are going to be comfortable to wait for 100% price rises before cashing out, but I think that such expectations can become a bit difficult to put into practice because for some other peeps it is going to be difficult to wait that amount of a BTC price appreciation before cashing out.. especially when peeps are already scared that BTC prices are going to reverse back down.
My personal approach has been to use such an incremental cashing out strategy to reinvest decent portions of what I had cashed out in order to buy back into BTC with dips. So far, I have found that even with reinvesting part of the value that I have cashed out, my incremental cashing out and reinvesting strategy tends to generate a decent amount of cashed out fiat (and perhaps my feeling even excessive amounts of fiat) in order for me to feel personally comfortable that I have plenty of fiat to work with to buy more BTC on dips or just to walk away with that fiat in the event that I chose not to reinvest it. On the other side of the coin, I also feel comfortable with the amount of BTC that I am retaining in my holdings because I will always have a moderate amount and I am never cashing out more than a certain proportion that I had previously established as acceptable for me (which in my full and complete discretion, I can re-think the matter and change those amounts and increments at any time too).
