id be extremely surprised if anyone on this forum backs ur idea of using paypal.

for the buyer Paypal is the safest option. They can give a try, since the chargeback option is always possible.

Your not going to stay in business very long selling bitcoins at nearly 40% discount.

it's just during the BETA. In this way you will be more understanding in case of delay. As I said, consider this as a 'premium' for testing the service

A hashed version will be stored in a database in order to anonymously identify you for your future purchases and increase your limit.

Wat?
6 seconds to calculate the hashes of all the phone numbers containing 6 digits
-> 60000s < 20h to calculate the hashes of all the phone numbers containing 10 digits

And this only on a CPU, imagine on a GPU...

Good point. Even though this is only to protect the database in case it's compromised, I am implementing encryption of the hash. Anyway, after the number is hashed, encrypted and clearly stated in the main page that it will not be used, consider that nobody is interested in a bunch of numbers with no other personal information. It is as useful as generating random phone numbers. Anyway, I am going to encrypt the hash.
