If you are buying bitcoin at a rate of $50 per two weeks then it would take 28 weeks to buy one btc assuming that your average price is $700 per btc (it is at $636 now).

I am curious to know how you got .02 from the PD faucet.

If you were to use "regular" faucets then it would take at least hundreds of thousands of hours of work to earn one bitcoin (hint: do not try this)
