Let me jump in: the BTC fraud (as well as fiat) is out of limitation period in most of the jurisdictions I'm aware of. At least this was the conclusion from layer I hired within EU to follow up my loss two years ago. Honestly I'm sure Simon knows it, as far as we know he also is long gone from EU, the BTC LTD is legally dissolved in the UK. There is small chance to chase this path as it might be still inside the limitation period in the UK (not the original fraud but the fact that BTC24 LTD was dissolved without transferring or mentioning the liabilities to BTC24 creditors = customers like us).
All in all it's safe to say that Simon was playing this forfeiture game for some time now (if not from beginning) and he is very well aware that there is basically nothing he would need to share with anyone here, at least not legally.
Let me follow up the story with even more writer's license. And please don't read anything in between the lines, don't take this as threatening and don't ask me for my sources. This is just how I see it (as one of possible realities):
- There was clear fuck up happening with BTC balances on known valets linked to BTC24 at the time when it went down (2013). We can only speculate how much this "freeze of German and Polish accounts by authorities" was really a cause or just a good opportunity to cover up bigger problems in BTC24 balances (namely these held in cryptocurrencies).
- The 72% payment of EUR/USD balances from user accounts which happened in <12 months after site went down were covering only fraction of the losses (only these few who followed the story and registered through that cumbersome process) and indeed no BTC balances. Now assuming there were people who had dozens and hundreds of BTC "lost" when BTC24 went off-line (and you may light up your imagination what kind of people with such credit could be) I'm sure there was some "silent" (or "secret" if you like) settlement happening between BTC24 owners (= which as far as we know was basically just Simon) and these specific creditors. People who followed the BTC flow from known addresses in first days and weeks after the BTC24 collapsed confirmed there were pretty large transfers happening.
- If this is roughly what happened then it's logical to assume that Simon lives with the rest of his (and our) BTCs somewhere in Asia (or elsewhere), simply far from his remaining small creditors, far from their jurisdictions and also keeping it low if case that they would team up and reach him the same way as the "big" creditors did in first weeks after collapse and demand their money.
- I wouldn't be surprised if he even lost the original balance sheets and I would be pretty shocked if he would have the BTC balances somewhere "cold" and untouched while paying his bills from his own pocket.
- I couldn't imagine how he would survive (and now I mean it literally!) the period when big creditors were looking for him without paying a lot and in case that majority - or all - of his fiat was frozen by authorities at that time he simply needed to use the only thing he got: cryptocurrency present in this (and BTC24 LTD) valets.
- To bring it back to Earth: honestly who from you would give any BTC (or even all/more then you have!) to some people crying on the internet that some non-existing company owe them some money and non-traceable crypto lost in 2013??? At the time when 1BTC is trading 40~50k USD and it's year 2021? With pandemic happening and no one really following the traces - so even if they find him in 1~2 years the legal window for fraud accusations will anyway be expired? No one. You would rather move to some nice place, hire a bodyguard and enjoy your life as proper internet villain!
