Except the share value is not dropping 7% per week.
Oh its not gonna drop exactly 7% every week especially not as long as investors cant do basic math, but on average the market value of the hashrate that your share represents, will. Now you can allocate mining revenue to increase your hashrate ('reinvestment') or pay it as dividends or do both in any ratio you want, but if you dont earn more in net mining revenue than the rate at which difficulty goes up, it doesnt take a rocket scientist to figure out what will happen.
Besides, as it happens, IPO was on May 23 @ 0.0975 Now 2 weeks later 0.072. -12.5% per week
But hey, enjoy the 2% weekly dividend for as long as it lasts.
so, AM is down more than 2000%.. What's the yield on that these days?, less than I can get at my local bank branch last i checked
Difficulty could increase 500%, we are still churning out BTC with some of the most efficient hardware on market
of course should that be the case we'd churning it roughly 5x slower (if theres no investments, no adjustments to dividend ration etc, but BTC is being mined nonetheless)
You don't account for replacing hardware entirely, nor previously accumulated dividends, nor liquidating hardware, nor selling shares. Also, You still didn't put your money where your mouth is either, the one that went like this: I'll give you 10btc if I'm a bagholder in 6 months, otherwise you pay me
