The platform has to prove it's usefulness, reliability, security etc before any biz will feel comfortable routing their customer's payment info thru the platform. Earning such trust in the crypto space is not an easy feat. That's why i say it will take yrs of proving it's viability before we can start discussing partnerships.
I think years is kinda harsh estimate, were not talking here about ebay or amazon, we are talking about smaller ecommerce sites in the beginning and they are usually not that picky and provide an excellent testing platforms for the start.
Even if it doesn't take yr for smaller ecommerce sites, it will still take awhile cos Utrust till has to prove that their platform can provide the security/reliability needed to encourage the routing of customers payment details thru it.
