Joining era swap is the best for us freelancers and other normal users who do online transactions as they make every transaction very convenient. They also gives us a chance of getting more take-home money from our work.
Yes, I believe Era swap has a lot of partners and investors the company/project will be successful soon, self-sustaining and will generate profits.
I dont think they have many partners now who support this kind of project. I could say that wallet service is in demand nowadays. But because of that it really affects the potential of every project that wanted to start . Some investors now wanted to see first the full potential of the product/application before investing.
I know they have big private investors who partnered and support the ICO from start to finish. Its just that they dont tell the people , atleast not yet . Lets just wait and see if the big companies that related to wallet service will be their partner in the future.
