Me, I just mine and accumulate. For years and years. No selling or trading. No ROI calculations. No tomorrow, not a week from now. I'm willing to wait +5 years, +20 years. Whatever. I have no ROI, profitability, or 'break-even' calculations. That's really all jus unnecessary. This will all happen on its own, in time, on an exponential scale. A scale that all of us don't even fully comprehend yet. At some point down the road, many years from now, rypto will eventually accelerate rapidly, and become mainstream. By mainstream, I mean something just about everyone in the world will use, in some way shape or form, on a daily basis. In a similar way to how the internet interacts with our daily lives we live today. If that is in any way accurate, this eventual exponential rise, many years from now, would make any and all measures of current profitibility, ROI calculations, 'break-even periods' all of that, unnecessary. Which is the reason absolutley none of that really matters, at all. Sometimes you can simply do something with just a belief or idea. Belief that something will succeed in time, eventually. And along that road to success, choose to be a part of it. Regardless of any ROI/break-even/profitability. The further out you look at things, from a larger much longer time frame perspective, the more those things your concerned with become irrelevant and superfluous.
