Selling to solve problems is a good way to describe a situation where a person is not able to focus on the long term, and surely poor people who stack bitcoin on a regular basis are likely to find themselves holding amounts of wealth that were not previously in their imagination, and so they cannot help themselves but to start to shave off of their bitcoin stash, and they do it over and over and over, even while they should be building their stash.. but it can be difficult to make progress when there is both building and cashing out going on at the same time, and the cashing out ends up either not being replaced or having to be replaced at way higher prices.  There might have had been 100s of thousands of satoshis, or even millions of satoshis built up over weeks in the past, but now those same quantity of satoshis might take several months to build back up if they are spent... so progress gets eaten into when a person is ongoingly cashing out some of his coins to solve various problems from time to time as such problems are always coming up, especially for poor people and once a person gets into a habit of tapping into his bitcoin, he doesn't necessarily appreciate that he is either eroding away at his bitcoin or he is failing to build his bitcoin or even worse failing to build his bitcoin even close to as fast as he otherwise would have been able to build it if he had stayed focused on ongoingly buying bitcoin and not selling any of it.
