Not that long, more like 2013~
Cool and bet people couldn't even get 25 bitcoins per find (mining) by then (2013).
Well it was a very different thing in early 2008 when SN contacted a few of us.
And that was just writing, no software/proof of concept yet.
Up to then no-one had done this before, all others like PE/EU's Peds were tied to fiat currency (ie.USD) or material (ie.Gold).
And before anyone posts without knowing this... a Fiat currency is legal tender with value backed within the country of, by government that issued it.
Anyways yes I was there in the beginning and when SN delivered the first version of a bit chain cypher basically btc was nothing more then intellectual study for the majority of us.
Other proofs of concept was some paypal transactions and back then a person could buy tens of thousands of btc for pennies and open a bitcoin fountains to slowly give it away to those who wanted to wait for them instead of just closing wallet and leaving those initial hundreds of thousands btc to rot.
Within a year or two there was several govt's threatened btc owners or at least people caught with btc wallets.
And I recall it was about this time that Steve Gibson and Leo Laporte did a podcast about bitcoins and a lot of gov'ts saw btc as a crime related item by then. Countries like USA, Canada, by then even China came up with laws or the gov'ts made announcements they would.
That's when many early adopters just dumped everything or gave it away.
Cause it cost nothing, was worth nothing, and it was nothing.
So now there's many BTC left trapped in the bitchain cypher without any owner and no way to recover.
I'm sure someone want's to be like Richard Pryor in Superman movies and find all those missing 1/2 pennies lol.
And yes the cypher chain has been hacked before and multiple times the entire chain gets reset when that happens and transactions are reversed, but often a lot of fiscal damage is already done and has caused some exchanges to go under in the past.
But a lot has changed since those early years back when bitcoins and mining them was nothing more then some interesting intellectual puzzle as a cryptological concept.
As time goes on and more people hammer at its insecurities, the more hardened the software and wallets become. Bitcoin was the first and the most secure, especially since all others walk in the shadow of that giant, meekly following in it's footsteps.
