But, I've read that you got about 0.02 BTC from the PD faucest, why don'you try to rent your signature to PD? Your max payment would be 0.16 BTC every month

!That would require OP to make 400 constructive posts a month, which is not that easy if he doesn't have much free time to spend on here.
Having said that, it is a good idea for OP to join a sig campaign to earn some bitcoin every month.
