Given that many of us wanted to get back into BTC for the bch airdrop, I think that bch should also be used to refund the fiat holders. Maybe at a discounted rate given its volatility. Can you explain why nmc/dash/PPC won't be used? If you don't want to push those coins on the fiat holders, maybe some of the BTC/eth/LTC holders would prefer them over the tokens?
Seems unfair to only punish those currencies.
Overall, IF you return, I will be extremely impressed.
