Thanks JJG for your thorough answer on selling on the rise and buying on the decreases!
I am also in an accumulation phase right now. The bottom line for me is that I'm long-term for this market, and my goal is just to accumulate as much coin as possible, despite price movements (though it can seem quite fruitless when your portfolio value drops in the short term, despite your accumulation).
Believe me, I can relate to folks who consider themselves to be in a BTC accumulation stage under current BTC price conditions because I was in a similar situation (pickle) in late 2013 and through 2014.
In retrospect, some folks may argue that I was more fortunate in my position and situation because BTC prices went down throughout a vast majority of that whole 2014 period, yet the truth of the matter remains that no one really knew where or when BTC prices would bottom, and such downward and flat BTC price performance did persist during a large majority of 2015, too.
During my 2014 BTC accumulation phase, I did not sell any BTC, and even though I considered myself to largely be out of my BTC accumulation phase by the end of 2014, yet it still took me nearly another year (until the end of 2015) before I started to sell some of my BTC and to take a more sophisticated approach to my BTC holdings that was more focused on maintenance, even though it also allowed for continued accumulation, too.
Sometimes, it is also easier to describe what is happening in retrospect, and by the way, I have a "friend" who is just entering into BTC, and who does not have a lot of money nor a lot of BTC.
That friend is considerably in a BTC accumulation phase that could take a few years to play out because that person is much younger than me, and by the time I got into BTC, I already had accumulated quite a bit of capital in other areas. Anyhow, for my friend, I am attempting to suggest to buy on the way down and sell on the way up, which would be attempting to employ a more sophisticated than what I had done for myself 3-4 years ago. Therefore, in this newly applied case, the buy on the way down is way more lopsided than the sell on the way up - which means that the attempt at that system buys way more BTC on the way down than it sells on the way up. Therefore, the selling of BTC on the way up remains small, but allows getting into a kind of practice to prepare for both ways and to attempt to take advantage of BTC's largely anticipated and continued price volatility. Therefore, such lopsided accumulation of BTC practice that allows for selling too is more sophisticated than a buy only strategy, while still attempting to focus on and prioritize BTC accumulation.
