Can you remember or do you happen to know what site could that time work as an exchange with a similar name, using e-mail address to login ?
I remember that I was login in using my e-mail and password to purchase or send BTC to others using paysafe card.
That was around 2009-2010.
I'm 90% sure that it was BITCOIN.ORG but I may be mistaken.
Thanks for your reply anyway !
I'm not sure honestly. The only (old) website that I know which used to accept Paysafecard is Virwox.com but, based on what you said, it's probably not it:
- The site started accepting bitcoin in 2011.
- A user must his his username instead of email to login.
You can try and google image the site to see if it's the one.
