So asking for a refund would give you a positive USD return...
If I'm not mistaken when batch #3 opened (was it 26th or 27th of March?) Bitcoin was around the same exchange rate as per today, ie $100ish... Maybe a little bit less ($90?), really don't remember the exact figure, but I remember making the calculation that in USD it costed aprox. $7,000
Anyhow, I don't care -
I spent BTC for a unit priced in BTC - what's this thing about "positive USD return"? Are you joking? Please be serious. Is like getting a USD refund for a pair shoes you paid in USD and thinking "well, I got a positive yen return".... LOL
I spent 75BTC and I get 75BTC back - full stop. That's break-even in my book. Or if you lend me 100BTC now you will be OK if I give back 100BTC to you in 6 months with no interest whatsoever, "because the USD/BTC exchange rate went up"? Very flawed logic.
