Every shop that handles payments in btc can easely add UTRUST, I mean why not? If you already accept payments in crypto, meaning you're somehow a crypto enthusiast, better integrate it with a platform offering buyer protection
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.
Yes you are right but, now is more modern and fast than few years ago. A lot of things could happen in a short period of time. Rumors like word of mouth, testimonies from client to client, sharing of experiences by business men to businessmen, news and socials medias and advertisements made through different networks will make a fast development and will make Utrust popular so fast if indeed clients both comsumer and seller are satisfied woth the service Utrust provide.
