to be honest, i still think the letter is too waffly.
do you think mastercard talk about dollars with paragraphs describing the cotton paper and patented ink. or the method of joining the chip to the plastic card, or the database link of the accounts.
i think there needs to be less waffle about the decentralised protocols and more about the:
no chargeback
pennies(3c) vs quarters(30c) fee's
hoarding for future gains
basically the practical stuff, not the protocol stuff.. after all if your pushing for coinbase/bitpay. the protocol and security is meaningless to a merchant as its all automated by a third party. all the merchant and customer see's is a QR code.
they dont see or know of the 'ledger' or the encryption stuff, they dont see it as being decentralised, as all their trades go through one company.. not random people.
(sorry for the backwar and forward thinking from post to post. but i tailor my sales pitches to each individual business and the more i read your letter pretending im busines xyz, abc efg etc in different scenarios, the more questions rather than answers i see them come up with)
