Anyway to change deposit address from miner.
Newbie here! Sorry if this is a dumb question.
I had my address set to Poloniex to deposit my SC coins from the miner, if I change the wallet address in my BAT file, will all the current coins go to the new address?
Yes, but...if you're mining in a pool, then the unpaid balance mined on the previous wallet address will not be converted to the new address. So finish mining on the old address until it's paid out, then switch to the new address.
Unless you have completely lost hope in polo, in which you need to accept the loss and move on immediately! :-)
