when I learned about cryptocurrency in general, Bitcoin was on its ATH, it was then worth about 20 thousand $. Then, of course, I started trading at the wrong time. It was not a very good experience, I did not know that this would happen, but when trading alts at that moment everything immediately began to fall. I even remember how I bought XRP for $3.....
Damn! I mean buying Ripple at $3 wasn't a bad idea but their issues with SEC ruined the potential.
For me, I started to buy bitcoins when it was pretty cheap, I believe maybe even a thousand bucks! But I was more into earning them for free (there were various ways those days) rather than buying with fiat as there were not many options either. Later I discovered BTC-E (right?) and that is where I started taking BTC trading more seriously and gathered good amounts.
