I have been selling credit card processing for 20 years, I know the costs & risks involved. We don't take micro merchants, I send them to Square, Square loses money on them.
Google interchange, you will see some interchange are higher than what Square charges. There are also Association fees on top of interchange, Carrier fees, bank BIN fees, costs of networks & staff, risk management (square fairs very poorly in this part) last but not least fraud, again Square takes anyone even druggies & #$%$, & fraudsters & they lose big on them.
The only way they could ever make money would be doing proper risk management, and marking up their costs, both of which they currently have never done, when they do that they just become another Independent Sales Office, albeit a much less organized one with less customer service, not a way to profit.
We all guessed their plan or end game, but before they went public, they never claimed to have one, so I guess they don't.
Google Checkout closed & now Amazon payments have closed, because you can't make money by losing money.
In my humble opinion, Square is worth minus, because it carries debt, but only takes on more debt, by burning money with no end in sight.
It baffles me why Blackrock invested other people's money in Square, all I could say is Wall Street is governed by frenzies, and not fundamentals. Being a casino, I have no idea where this could go, but in my opinion the real value is zero.
Tonight's report may reveal what I have known all along.
