There were a couple of reasons, one of which is they did not want to sound like they were an insure provider. Here's some news on them.

Having worked in healthcare and knowing enough about managed care and the litany, this is actually big news. To partner with a re-insurer is great validation. The funny part is that the price has gone down since. As Warren Buffett said, "the market will remain irrational longer than you can stay solvent." I don't own much of this at the moment. I want to buy more but am too lazy to deal with yobit and since a lot of my stuff, I hate to sell. Hope it doesn't bite me in the ass. Then again, if news like this can come and go, I think IXledger/IXT could stay off the radar until it hits a bigger exchange.
