Crowdfunding withing the US residents has a lot of regulation and that's the only barrier as far as the custody of crypto even though difficult not impossible but the actual asset t's risky also because it is a volatile asset and any cryptocurrency therefore for US residents unnecessary to raise funds through (unless using stable coins) crypto since the US dollar is what most end seller would require.

Oh, by they way, owning investment real estate is a business.Here's my not meant to be a political statement, statement:  We are entering a new Golden Age of Opportunity for Business. 

With four plex you have to pay utilities for the hallway and common areas, also maintain and clean the common areas, because the tenants won''t.

However, I did make a purchase in Pgh that is cash flowing,  but no equity so now I see more clearly what you meant when you said it’s better to have equity in the long run. 

IE if you are wanting to wholesale which I don;t reco today, its too hard, you want a list of high equity owners BUT BUT the value is in figuring out a source of stress, a reason why the owner is on the virge of wanting to sell. 

.: I get what you are trying to do and protect, but this is a very slippery slope to get into....In the veterinary field we see this all the time....upset clients going on social media and trying to destroy vets and clinics..... and a lot of the time post complete bullsh$t and inaccurate accounts of the situation.
