I'm not sure of the full details as to why AT was never implemented on NXT. Whether that was your fault, the NXT devs, or some combined form of both, I don't know.
Then it would be appreciated that you don't make false "scamming" accusations. Others *do* know the details and as has been pointed out the final word on AT being implemented on Nxt was Jean-Luc who said no (and AFAIA he never changed his mind about that).
If you're still willing to refund me, I'll take it. Let me know, and I'll send you a bitcoin address to receive it.
I can't just take your word for that (as you don't take my word for anything that's only fair IMO). Also you seriously deleted a Bitcoin wallet without keeping a backup of it?
If you can provide reasonable proof I will refund but just saying "I sent you 1 BTC way back then" isn't very reasonable proof (as no doubt others would suddenly start making the same claims as you are).
