There are exist another "PayPal" for crypto. Utrust making similar platform and in the end of this year this must be released. And some other projects developing same. What advantages you have before this projects?
I believe the market is big enough to support multiple similar projects, no need for one to be above the other.
Before any marketing is taken to the limit I think that the platform should be working to its fully extent.
I doubt it will be fully working before sale and if you want the sale to be successful you need a lot of marketing.
I don't know these days. People are more careful when it comes to investing in just a white paper.
Many scams in crypto world have embarked on people, it is understandable that investors are looking for something far more than just the WP.
Not only that. Control measures like escrow needs to be in place and of course as much transparency as possible.
DAICO model might solve those kind of issues,various projects are trying to sort that and implement something similar.
Agate has app that everyone can try before investing,and thats quite important,to have something more than a whishlist called "whitepaper".
