By now, we can buy real-estate with Bitcoin in countires like the USA, the UAE, etc. The project has excellent ideas, which can be further developed. But the question is how to keep the project really under development and on track? there are abundant abandoned ICOs.
You are absolutely right about buying property for Bitcoin in different countries. But though, it won't solve the legal problems concerning buying and selling property in different countries. So you will face huge variations of law. And as we create a global platform for real estate, using iDeals (better version of smart contracts) and varois services within our platform, it will be easier to conclude deals in different countries.
And as it was said before, we rely not only on crowdsale campaign to raise funds but also on more classic ways of financing.
