Whoever is saying the Bitcoin is a scam is a mad or nothing. But, is a better solution to PayPal. This is a fast transaction method worldwide. But, gradually it is synonym as a currency or the coin.
Paypal is actually faster, but its fees are high as well... As of this time, I wouldn't think about transacting in Bitcoin since it obviously isn't practical.
Now they are mentioning bitcoin as scam but previously PayPal done lot of transactions but now why they are taking such decision commenting negative on Bitcoin. But soon bitcoin will be accepted in Pay Pal.
