Wasn't really easy buying in 2010.
To give an example (mine)
1) Transfer funds from Bank to Paypal (2-3 working days)
2) use Paypal to credit Virwox (Hungary Exchange) 2 working days
3) use Virwox credit balance to buy Linden Dollars (Linden Bucks) 30 ish mins
4) use Linden Dollars (non blockchain but basically a stablecoin) to swap for BTC
5) withdraw BTC
Then when you wanted to sell, you had to hope there was demand, and you usually ended up with tonnes of wallet with btc that wasn't worth much and lost/forgot about.
Also it wasn't a investment back then it was a means of exchange (in my case exploit test kits for servicing clients security in the early Web 2.0 era).
