Thank you for your reply. No. there is nothing there. in the balance page and transactions, there is nothing.  However, the first time I tried few days back for like 1 hour something, I got a small amount which I withdrew to test my wallet. it worked. So in transactions, my previous one is there, both the credit and debt. but after that for the time that I said I have been mining, I do not see anything new in my balance or transactions.
 

Hi,
I am very new to mining.
It has been for almost 20 hours that I am continuously mining XVG with 630 MH/s, however, I have received nothing in my balance.
is that normal? what happens if I stop and start again after a day. do I lose what I have done or what?
Sorry if my question might be so stupid to you guys.
thanks.
