Marvin, are you stupid?
Who is Marvin?
9.9 - 1.1 million dollar villa means 8.8 million USD. Now their 680 BTC + 6500 ETH is worth 8.2 million usd. Taking, in consideration $250,000 burning rate for january, it means that now they have only 7.9 million available. Also, I have seen that they round up all the numbers. They also have only 6,400 ETH available and not 6,500 ETH available as they have been lying in the AMA to make the number a little bit bigger than in reality. So, I can bet many of the numbers were increased.
They can always have more accounts than the one I found. I would expect them to transfer smaller funds from the multi-signature wallet to a single-signature wallet, so they can have easier access (UX for most multi-signature wallets just sucks).
Also I just rechecked my numbers, and they actually have more than 6500 ETH (my 6400 ETH was rounded down, so it was my fault, not theirs): 1,073.38518119 ETH (@ 0xEFa351D189c367D109859AFdF6f3D17EEb0825a5) + 5,457.0405 ETH (@ 0x847C590d780913B394290295A26EA172e12fFbF1) = 6530,42568119 ETH. Again this is a lower bound, they could easily have more than that. So it looks like they were actually not rounding up, but rounding down. Maybe they wanted to trick us into thinking they have less than they actually have.
The AmA was done on Jan 11, so you shouldn't take the whole 200k USD monthly burn rate, because this is only half a month ago, but only deduct something like 100k USD.
Also you are now taking today prices for BTC and ETH, so to be correct you should also evaluate the ICO funds accordingly: 60,000 ETH (which was what they got in the ICO) is 6,955,082.24 USD today. They still have 6500 ETH left, so they only invested 53,500 ETH, which is 6,202,149.78 USD today. From 6,202,149.78 USD they were able to diversify into 1.1 Mio. USD worth of real estate (not a villa, they said its empty land in the AmA), 5.1 Mio. USD in cash and 2,415,400.80 USD worth of BTC (680 BTC at current price). If we consider only the Cash and BTC as movable funds,
they still managed to earn 1.3 Mio. USD (made 7.5 Mio. USD from 6.2 Mio. USD) beside buying the empty land and all compensations and payments. So if you take it that way, they actually performed very well and had a net positive first 1.5 years, to be precise it is +21%. (I am not really serious about this now, just saying that your calculation also doesn't make a lot of sense). Given that they already delivered way more than half of what they proposed during the ICO, even -50% would have been fine to me.
But I still don't know why they actually should lie at us around this numbers? Could you explain what they earn from putting wrong numbers out (which probably is illegal given they are a Swiss non-profit foundation)? I don't think these saying have any influence on the price of NIM and I also think they are not very interested in increasing the price of NIM (at least until now they did no marketing in that direction).
I totally understand that some investors (by the way, you are still pending to proof you actually are one) are upset about the price. I might be too if I hadn't earned more than I lost through clever trading (or luck) of NET and NIM. But fortunately for me, I am still net positive with my Nimiq investment and as such am not blinded for the progress they are doing (for example in scalability research or UX improvements). If the NIM price wasn't that low, nobody would even care about their financial details as we do right now...
