Do you know how/where zpool gets their exchange rates?
I'm not sure what exchange zpool uses; crackfoo will probably comment.
I have seen the down ticks when the coins are sold at exchange as well. Seems like a large percentage drop between block found and sold; but... honestly with how crazy the markets have been, its no surprise.
I myself; see people carry the distinction that BTC is separate in price to the dollar, etc... but when anything bad happens to BTC to cause the price drop; its not something bad happening to BTC 99% of the time, it's something happening focused on trust in others holding your coins or the exchange to fiat.... that's not a problem with bitcoin when its used as intended =) I can tell how well my profitability is going via my 3 month grand-total [which is decreasing]. I think by now most if not all of my rentals should be off the list, and maybe even the larger machine up north I was mining into my personal account with as well.... So... Yeah. Curious to see for sure.
Anyways; since block find time (pool luck) has been below my normal batch... i'm curious at how well lbry keeps paying out in the next week to two weeks.
