Wouldn't potential investors dilute AM-share profits/dividends? Or is this a good thing (stability, bigger ventures,...)?
Depends on what they are investing
in. Right now the BTC community sees little reason to invest in AM because they basically aren't performing, so curious to see why others would pile money into this venture right now.
The BTC community is incredibly short-sighted. Investors are called investors for a reason. They look beyond a week.
A lot of folks in this community look beyond a week as well. Falling dividends, failed gen2 hardware attempt, nothing but future dates for gen3 (so kinda like KNC, it's a plan with some dates attached as of right now, just not selling pre-orders), and no comment on the liquid cooling business. There is a theoretical limit on how much folks are investing in this death-spiral to the bottom that we all know and love as mining, if folks like KNC or even CoinTerra manage to start rolling out 2TH+ devices that's about the end of any guesstimate for network speed or ROI on hardware.
Long-term => we're facing the brink when the block reward halves again, but long before that we're going to get to the point that basically only the vendors can afford mining equipment anymore because there will be no room for margin. When everything on the market produces negative ROI, people will stop buying. At the end of the day, people will stop "investing" too because in the long-term there aren't any real benefits to keeping money in a venture that is continually depreciating. Yes there may be a bump up in however many months it takes FC and crew to release more hardware or capture more of the network hashrate, but most folks who paid into AM shares likely won't even get the fiat value of their original purchase back, even with dividends included. Sad facts.
So yes, folks in the community can be short-sighted, but long-term there aren't many good reasons to keep cash in anything but BTC. You can liquidate immediately, costs zero power to maintain, you can trade and play the market to possibly profit, and you aren't starting at net negative (some people will call it sunk costs) to attempt to earn your money back while a vendor profits immediately. Believe me, as someone who owns AM shares I'd love to see them rise from the ashes and become a market force again, but I have next to zero faith in this happening. Like playing the lottery, I have my tickets, hope they pay off one day. But not counting on it.
