Can these 2 exchanger site be trusted? Have you done any transaction on these websites?
I highly doubt it.
Only because I never even heard of these exchanges until now. Why would someone try something unknown to them, when they can use known service like localbitcoins...
I think its risky to risk your money in that 2 exchange sites.. better to withdraw your money from paypal and try to buy in local bitcoins or use perfect money many sites are trusted there.. like changer.com
