The backing fund is looking good each week as you have added some very good coins to it recently with DNR, XLR, IC and even XMR. All of which I think have good solid long term futures. I do think that we need another exchange though soon as people don't really like Stocksexchange all that much so hopefully it won't be long for another exchange which will also help with volume and then a CMC listing which is vital for any coin/token as it gives exposure to people looking for new projects like Passivecoin.
I agree may try Bridge and see what you have to do to get an add on it, but overall its a very promising project in its infancy that I plan to own a few thousand shares too myself!
The dev has already contacted CryptoBridge and they need to first add Ethereum and Ethereum based tokens first and then I think we will see Passivecoin listed on there. CryptoBirdge is getting a lot more coins listed weekly so I'm really hoping that soon they will start with Eth based tokens and then we can see PAS listed. I think this exchange would be great for PAS.
