I still wonder... how does people could generate a private bitcoin key in 2009/ 2010?
Possibly that many people looking for a wallet but there wasnt e-wallet sometimes...already Private keys,, I'm sure lot of people missunderstood on that...like me I did.. I was looking for a wallet but actualy, Private keys hOLD Bitcoin, not the e-wallet...
Kind of bitaddress.org (already been there in early 2010)?
Thanks to all people who replied my messages till now!!
The way you generated a private key in 2009/2010 was with the official client. There weren't other implementations, and there weren't SPV services until 2011 ish so there werent any "blockchain.info" webwallets, let alone Electrums and so on. So Bitcoin-qt was it.
If you wanted to buy on the ancient markets (like bitcoin2cash) then you had to manually do the whole thing. Send an email, wait for a deposit address.. the whole lot. I guess you could have automated this with javascript by having a ton of deposit address and hand them on request but I reckon it was really primitive stuff and you had to email dwola which I think was the admin of that site or he ran a similar one.
