I beat you hands down. But I am not stupid and will not say exactly by how much. Your compounded ror is 259% a year. If we take your return on january,1 2017 at a price of $773 your 166 becomes less then 9. Your compounded ror is then 106% a year. 2017 was a lucky shot. We will see if this pace can continue.
As daytrader mine is much higher and stable over the years. I always do over 100% a month on the amount that I invest in daytrading. And that amount is surely bigger than your initial investment in bitcoins.
Your risk was none???? What a stupid statement. You only knew that your risk was at max a total loss, all the rest you could not know with certainty.
You built and sell trading software???? LOL. You just proved that you don't even know what "drawdown" is. You had several big drawdowns. Those who know what a drawdown is will confirm.
"Hugely" is also a word without any meaning. For some 2 coins is huge, for others 100 coins is small money.
