Couldnt you find a more dead project to issue colored coins than Colu?
Here is their topic https://bitcointalksearch.org/topic/ann-the-official-thread-for-colu-a-colored-coins-protocol-api-938554
Those guys seems like they took their 2.5 million seed round, went on vacation and spent it all, they haven't done anything since then, 1 year and still the same beta and mobile un-friendly.
only 6 posts on 2015 and no activity since then, when do you expect exchanges will add their coin ? 2022?
the level of honest scams is rampaging, you are very cynical or you in fact don't know anything about the current crypto market.
