Not a crazy idea at all. I have some longer term plans to attempt to merge “regular” investments with colored coins/open assets. @dazme and I have discussed the idea in length. As @quigley says though, the biggest hurdle is the get rich mindset of 90% of the crypto space. This is why I am approaching ABC the way I am, making sure that people understand the long term planning and those that get it will be in for the ride, the rest will wish they had when they see the asset having been around for a “long” time with consistent payouts and growth, assuming I am successful, though I have to “know” that I will be or else I risk not.
If someone wanted to setup a company and the infrastructure as well as jump through the requisite hoops, you could easily have a hybrid investment. You would have 2 sets of investors, those that want to get in via check and those that invest via btc, with the asset running on colored coins, the firm handling the fiat investments would manage a wallet that held the asset in colored coin form equal to the share of fiat brought in, this person or persons would then cash that btc out and pass it on as needed to the fiat investors. You would also have the opportunity to slowly on board more people to the idea of colored coins, btc, etc.
Truth be told, it really isn’t all that complicated to setup a small investment group for the purposes of real estate investment, the only real issues would be strictly logistical in nature, re the above paragraph.
