Converting like he was saying is not mainly the easiest way to earn btc's. Bitcoin price are not stable and even you had a full contol of it the one you will control here is your guessing ability and I found it hard in my part lol.
Actually my first purpose to earn bitcoin is not to hold bitcoin, but to convert them to the fiat and to reduce the fee and time, because bitcoin is most simple than other payment processor i.e paypal,as i know that bitcoin's fee so low and no need long time to convert them to the fiat so this is my fastest way to withdraw my money from paypal to fiat,i sold my balance on paypal to my friend and then he sent me bitcoin
If you look at the exchange currency you can see that it's hard to find anyone that will accepts PayPal so i think you are lucky.
Maybe your friends is not taking any commission, what i would suggest you is to take a look at the bitcoin debit cards.
They are different kind from different providers and different fees, maybe this could be better for you.
I knew it, because to trade paypal balance its so risk and paypal did not allow it, so its hard to find people here who exchange paypal to bitcoin or vice versa, yeah you know its like mutualistic relationship i need bitcoin my friend need paypal.
And about bitcoin debit cards i heard that we should paying monthly fee right? and cashout's fee is to high really?
Well you have to make your own research about the new bitcoin debit cards.
There are many that offers free monthly fee for the first year, like bit-x and xapo.
