I think you might be onto something here. I was just thinking about what you said - preferred or common?
I'll bet that's how he ended up paying 0.0033 per share - he must have bought preferred shares. The preferred A shares convert to common at 0.0033 per share. Frederic already had 100,000 preferred A shares and they convert to the 30,303,030 common shares. You can see these numbers in that pic from my last post about this.
Easy enough to do the math, divide 30,303,030 common shares into the 100,000 preferred shares (they have a stated value of $1 per share) and you get the 0.0033 which is the price he and Jan and Ulf paid back in Feb 2016 when they each did those $100K subscriptions. So must have applied that $50,000 loan to buy 50,000 preferred A shares with that loan money. Clear as mud, right :)
