I was seeing that real-estate related crypto invest ico was failed almost 95% so how you can believe this type of ico? you can invest over too much better ico's far better than real estate crypto projects.
Im definitely agree with you , but more than 90% of other non real state icos were also failed...
I think its not depend on weather the project is real state or non real state , its depend on the team , partners , aim , roadmap , concept etc..
