Hi, Please . .
Please, help me uninstall Bitcoin-qt wallet from my windows7. My C: drive space is diminishing day by day as the sync goes on.
How do i delete completely??
Please suggest me some online wallet.
Can i change the bitcoin address in the GUIminer to a new address
Well, BitCoin-Qt takes about 12GB of disk space if I'm correct. Delete the Bitcoin folder in C:\ drive, make sure you can view hidden files and then open Start and type in the text box "%appdata%" without the quotes of course and delete the Bitcoin folder in it. I'd recommend you MultiBit, it's not online wallet, but people use it as BitCoin-Qt alternative, it doesn't sync so long and doesn't take such space on your PC. Also you could try Armory, but as far as I know for that you'll need
BTC-Qt, so basically switch to MultiBit...
EDIT: Yes you can change the address in GUIminer, but you'll have to edit the miner.
