You should never start a new or experiment/test out an ICO launch without a fully prepared pitch. You automatically loose more than half of the interest you might gain after the announcement. Unless you are being pressed by your investors i see no real reason why you would not invest more time into a better pitch. But hey, that's just my two cents
The real estate ICO idea is one of what i call a "Future everyday commodity" idea. When the blockchain technology develops, at a certain point, such real life transactions for common exchanges will become obsolete and automatically will start using blockchain. Shopping of any kind (with some exceptions here and there) will be done in parallel with real money or fully token based.
My initial thoughts about this - there's either going to be one big FinTech company running local token exchanges or even a whole corporation running it globally. This means that probably the first company to start and be successful with their ICO will have a leading chance in becoming that corporation/company running things.
Blockchains at the present time are producers of flagship companies at their respective industries
Good luck, Bob
