Sounds like you’re mining solo. If you want to see some Zcash anytime soon, you should join a pool. At this point it’s your 4sol/s vs something 7.5million sol/s network wide. Those odds aren’t good.
I’ve had a good experience with the zmine pool, prompt, reliable and friendly. Should see a block about every other day depending on the ebb and flow of things. Larger pools will have more frequent blocks won, but your share of it will be smaller. In the end, it’s even no matter where you go, so I recommend smaller pools for the health of the network and service and support.
