It looks like it was indeed probably ten. Just assuming by the amount of USD accumulated. At that time, Bitcoin was barely popular so this must come from a person that probably knew about it because they were in the same town Bitcoin was developed in or something. I don't really know. Just speculating.

If I may interject here: One thing that can be done is to just focus on yourself when you're here. Nobody wants to just throw away all their precious earnings on people that will probably just blow it all away. It's not that easy to come across that much money. Not only that, assuming you held your coins when they were just $10 each, it took you years to get that much and that'll never ever happen again. Bitcoin is a really risky thing to get into. Whether you're gambling, investing, spending, or even just holding, it's all a huge gamble.
