So what should he do if someone donated at 35k satoshi and he turned it into USD?
Pay the difference by himself?
Obviously. People were telling him not to cash out the coins for just such a reason. He ignored them.
If the price had gone up, then he would have made money in the process of returning their donations. He accepted that risk once he decided to cash out, and the WS event didn't go ahead.
well i appreciate it would be hard to refund everyone but as you like to tell people, you have a lot of money,now,
as i see it, you made the mistake of cashing it all in for fiat so you should make thedifference up. you have no right to decide to donate all of it to the red cross, sure it's a noble cause but some people might like their dollar back. it's their money after all.
