I’m sure there are a few hurdles, but wondering what is the biggest reason that keeps us back at this moment as the most pressing thing. Is it that the technology just isn’t there yet? Or is it because of legal complications, international treaties and all that? Is it just not financially feasible to do at this present time with the technology we do have? That we could do it, in theory, but the ROI is too low?
You should take into consideration that AFAIK none of these companies have launched anything, let alone started mining.
Of course, just surprised they actually exist.
Then again, I guess it shouldn’t be a total surprise since people are trying to raise capital and invest.
