that pool has a crazy high difficulty   1,000,000

so it does not easily  register your stick.


Do you realize  that  pointing a stick at nicehash is pretty short of earning money?

you have 23 gh   that is about   15 cents a month in BTC


go here and punch in 23gh

I suggest mining at pools like

you get the same 15 cents a month  but if you stumble on a block you get a 1 btc bonus
