I understand (and share) your concern - but I also don’t want to over-react to short-term market events. Bear in mind that miners can easily leave MPH at any time, and as far as I know, they don’t actually run a mining farm.
Yes, it’s looking like that will be necessary. What other pools offer an Asian IP? I still suspect a lot of their popularity comes from a smart decision to support the Asian mining market.
That’s going to be a tough sell - bear in mind that the 0.9% they charge is not just for BTG; that’s what they charge for all their pools.
The alternative is for the other pools to lower their mining fees, to offer better service, to market themselves better… they also need to compete.
