I just went through all my old wallets, and unfortunately, I cannot find the tx / address I used to send you the one Bitcoin.
So you admit that you cannot prove that you sent me any BTC at all (and that you have now checked all your old wallets).
Case closed in regards to trying to obtain BTC from me (and you are looking more and more like a bought account trying to do so).
It's funny why something that allegedly happened so long ago would suddenly be brought up - but then again the price of BTC only just rose quite a bit recently so perhaps it's not so surprising after all.
The facts about what happened to AT are known by plenty of others so I really don't care much for your conspiracy theories (especially those supported by scammers).
Also as soon as AT appeared on Burst it could have been added to Nxt (as Burst is a Nxt clone and is open source) but clearly no-one in Nxt was interested in doing that. Still somehow my fault?
Another thing is that "my role" was to provide the design for AT and that was in fact delivered (in the form of the specifications that are still available on my website). Getting AT to work in any coin was never actually my role at all (which is why others were involved in the project).
There was never a crowdfund for the development of AT with promises of refunds if the job was not completed (but that seems to be what you are implying was the case).
Finally - if you had read the "announcement" about the NxtAT Asset (which I didn't create btw) then it clearly stated that the main purpose was to fund development (and that is indeed what occurred). You should realise that the other two working on AT received the vast majority of said funds (and I returned all of the NXT) so perhaps you should be pursuing them for refunds (although - again - it was never a "crowdfund")?
