What does on exchange mean? And what of all these coins that seem to have a small amount of coin on exchange that I cant see in my wallet? Still confused on this whole deal.
And why does it take what seems to be unreasonable amounts of time mining zcash at 1.1k to display a proper credit of any sort when mining. Is this normal??
"On Exchange" means that mined coins are sent to exchange site like poloniex, bittrex, yobit.
Maybe they are waiting for exchange, or already exchanged to target coin and waiting for withdrawal.
As there's some minimum trade value, minimum withdrawal value limitation from exchange sites, there could be some little amounts here and there.
Pool collects them and exchange/withdraw once when certain conditions are met.
It takes some time if coin is rare. Pool give back those coins that are so rare and stuck at exchange site for few months. (I cancel exchange if someone asks about their coin)
Zcash luck goes up and down like roller coaster because of small pool hashrate. You'll get appropriate amount but it fluctuates daily.
