I think it was most likely in the 150-200$ range when i first started trading. Before that i was just messing around and getting familiar with the scene. Now that i think about that, thats nearly x200
I second this. I bought my first bitcoins at around 80$ and started trading them a few month later until the price rallyed to about 1000$ in 2013. This was the time when I stopped my trading activities back then.
However, as I was a complete novice in this area at the time, the losses in BTC terms were also quite high - but quite bearable in dollars at the time. But I would still very much like to have the BTC now
Now to think back on it. It really shows the power of holding aswell. For every 1 dollar i would have put into it i would at this moment have 250$. Thats a wild return! I know that people who are good at trading, understanding and finding trends would easily beat this (especially when crypto was wild at the starting years) but even by just holdings the potential is there.
