Great video, Heidi! It truly is beautiful there. and I have Vietnam on our list of places we'll visit someday.
There are a lot of ICOs that launch prior to the product being done, but I think this is one of the most widely distributed ICOs we've yet seen. I've already built the current development version of EOS myself (I'll post on that soon), so I know it's not vapor wear. Dan's trading on his reputation and the history of what he's already accomplished and some are upset about that. For me, I think he's earned the right to do it and clearly, the market is supporting it with over $3M a day flowing his way.
That said, I completely agree with your caution, and I'm glad you put it in there. No one should invest in things they don't understand or take risks with money they aren't willing to lose completely.
