You'll need to address the naming issues with Visa for investors to feel comfortable.
It seems likely that consumers will confuse 'visacoin' epayments with other Visa epayments in the 100s of countries where VISA owns intellectual property protections.
If its confusing to the consumer it is unlikely to survive a challenge in US courts. I don't know how it works in other legal systems.
Thank you for your opinion.
