More proof that something stinks in the state of denmark.
If you invested in july and since then the NAV of the entire basket has dropped 30% since then, to be generous with the #s, then the BTC value of your account should have dropped as well. Your 0.14btc invested should be worth 0.098btc. I would say that you need to account for the staked coins being cashed out but its clear that he has been using incoming funds to cover payouts, part of this is understandable, it saves on time and tx fees, but it appears as though he hasn't sold off any of the underlying coins. My guess is that he is hoping for the day that they "go moon" and he made money by ripping people off.
You should check out the staking pool asset that I recently launched. I will be picking the coins we stake based on several criteria one of which will be to look at the charts and the inflation rate and look for ones that are bottoming out or might be, with some skill and luck I can pick coins that won't sink much more in value. And of course I will be sharing a NAV for each satoshi invested and will move to NAV priced pricing for the shares when the pool is large enough to warrant it.
