You are absolutely right, but that detailed whitepaper shows community that they are serious about their project and i think they will follow the dates that they set everytime.
ofcourse there will be setbacks but i believe this team can handle those setbacks.

jep, i also think that EHF are serious about their project.

this isn't a security so I don't think they'll exclude US citizens.

Then that's good news, banning US residents due to SEC inv. can lower the interest or the money that raised. Hopefully things won't come to that.
But ehealth is a long term investment so everything is possible.

One problem with long term projects is that the rules of the crypto world change much faster. Now it's possible to workaround the SEC with utility tokens, next month maybe only pro investors with an income over 100k are allowed to invest in any ICO. Could even pull a China, having to refund prior investors. Who knows what those kooks are up to.  Maybe it's time to start thinking about a plan B.

This is a risk that every ICO has to face. Many of them simply won't accept American investors. I'm sure the team has legal counsels.

Yeah they're one of the best in the field

every projects wants to hedge their bets, it's natural , lest the government come down on them. this is a new field and there will be growing pains.

When you consider how much they have spent time preparing your project, I can conclude that all decisions are carefully weighed and thought out.
