If it makes you feel any better there were a lot of alt-currencies around that time. Many were marketed as being untraceable to avoid government interference and taxation. And many were used for laundering, drugs, and childporn.
Around that time I was aware of bitcoin but I was paid for some dev work once in e-coins and had the hardest time converting that to cash, which is how I paid rent. And while it made up a small part of my compensation I thought it was ridiculous. Something tinfoil hat wearers cooked up.
It's easy to say it bitcoin was going to be big, in hindsight. I used one of their early ATMs to pay for pizza. At the time it was trading for ~$2. I didn't think much of it until years later when it got a meteoric rise.
