Welcome to the BTClock party!

Check the kano.is > Help > Payouts section in case you're new to PPLNS mining.

Basically, you get ramp-up payouts until you're mining at full capacity over the last 5Nd, and you get ramp-down payouts if you ever quit mining until it's been 5Nd since you stopped mining.

If you need a visual, check your Kano.is > Worker > Shift Graph as each new ~50 minute shift gets added.

Last thing: You might want to join Discord for more discussion (via the kano.is home page).
