Hello again.
I thought a little about Golang/SSL, implemented in DERO, and have some ideas. In theory the use of DERO for exchanges or PSP (payment service providers) will provide a more stable/privacy/secure connection with users and services.
Also it can give more in different web-services what uses a lot information about their users and need safe connection.
Besides, adding the NFC to a mobile wallet can give us a good and secure payment instrument.
