The same as anyone else in Bitcoin, I think. Obviously I want to maximize the market capitalization of my product. If I keep the bitcoin, I risk devaluation, whereas if I cash it out, I risk losing out on potentially huge market gains. I want to encourage the market, in any case.
That is what I do as well, I'm considering purchasing Bee based on my trial of it this morning. My only concern is in keeping enough clients around that I need to use it! But actually, for me, this is the kind of native client I didn't know I needed (I spend way too much time in Jira...) and that it hooks into GitHub as well is a big selling point, since that's pretty much how I divide my personal work from client work. The interface is slick, although there seems to be some stuttering when I move the window. I'll probably buy it when I get my next paycheck. And maybe if I write a blog post about my own app that has sold 12 copies, I'll sell a few more! ;)
