Pairing the price of MIO to fiat protects those that invest with fiat currency but it doesnt protect those that invest directly in ETH/BTC. Did you think about that? A lot of people invest directly using eth/btc. This way they are protected. With your solution (the one used by IRM), you get the exacte same use case for people investing in BTC/ETH everyday as the price changes.
Its not a simple choice to make since both way can have issues. And you should know the risks of investing in crypto with that high volatility.
When they are buying equipment in FIAT the smart thing is to set the token price in FIAT. Like all other mining companys did.
Sadly Miner One is not run by intelligent people.
Even worse is that instead of fixing the problem they pretend everything is ok.
Now, me and other people that got in early are looking at 1,5 years+(even if price of ETH goes up) to get ROI when new investors will it in 8 months.
