Hello every one is there any way to convert btc to paypal for free
You want somebody to buy your BTC with PP? I'm sure there will be plenty of people who will do this, but you're very likely to get scammed.
I have sold a lot of BTC for PP on localbitcoins.com and have never been scammed there. I only use people with over 100 trades and a 100% satisfaction rating. There are a lot of reputable vendors that meet this criteria on localbitcoins.com.
