Some online cryptocurrency exchanges may sell bitcoin through paypal. Some are legit and some are scams, but I would say majority of them are scams. I recently received 76$ Paypal and tried to buy Bitcoin through a website. Since it looked kinda fishy I went ahead and only "bought" 5$ worth just to see if it was legit. I waited over 4 hours and there was no bitcoin in my kraken account at all! There was absolutely now way to contact the website owners so my 5$ was gone.
I'm not too upset because i'm glad that I didn't lose all 76$. So guys, just be careful when trying to purchase cryptocurrency. This market is still a baby so now scammers are shifting into this market to steal investors money.
Also I came across this website called jet-coin.com. They claim that if you give them 1-15 bitcoin they give you 3% of that everyday for the rest of the time you keep it in their. Was obviously a scam because a week before that the website was completely different and offered 15% every day and your bitcoins doubled every 2 months.
Be careful steemians! Steem on!
