Hello, i have been mining BTG for two days At what point do you get an actual balance

You're more likely to get a payout first before you get a balance indicator. That's because you're mining with a small number of other miners and so blocks are not being discovered frequently as on larger pools. However, when each block is finally discovered the payouts will be much larger than what you're likely used to. In my case I mined for three weeks on the Ethereum pool before we all got a block reward. My payouts here have been very rewarding. It just takes more patience.

PS, the balance indicator will only become useful in the future once the pool is much larger therefore discovering blocks often. The minimum payout threshold isn't really playing a role now so block rewards will go straight to the miner rather than into the balance indicator. But again, patience pays off handsomely in our small community.
