I browsed the Tezos announcement thread and I can see that most of their investors are still very optimistic about the chances of the platform's success.
Maybe it will be, but if the Breitmans treated a cryptocoin project like a start up, and problems about money arise, then it does not look good for the start up, I reckon. We have already seen it happen in the past. Also remember, only a small percentage of start ups reach success. I have read that 90% of them all end in failure.
More than 95% actually in the next few years will end in failure. Especially in cryptoworld where to find money is much easier. I also bought tezos on the ICO and I'm not so optimistic about situation. Technology could be good but these people looks like scammers.
