They did invest in WeTrust, it just hasn't been announced yet. Maybe there are other unannounced investments too.
They also did a fantastic job of holding and letting ICNP's BTC and ETH appreciate. Especially with POS coming up, $40 or $50 ETH will be a thing of the past, just like $200 or $300 BTC.
There's a new crowdsale every week, so even if Iconomi misses a profitable one, they have BTC and ETH stashes big enough for years of ICNP investing.
Two of ICN's biggest competitors, MLN and BCAP, dumped all of their ETH for ~$11 and ~$44, leaving them with ~2.5m CHF and ~9m USD in fiat AUM, respectively
Considering this, I'd say Iconomi did a damn good job holding all of their ETH (minus Santiment and Wetrust) from $13 to $75 and beyond.
In fact, Iconomi even bought 5k ETH @ $10 using some of the fiat that was collected in their ico to make the Golem investment.
We like to joke, but it is looking like Taas may actually be serious competition for Iconomi, because they are still holding a significant stash of crypto.
